[Indic-computing-users] Problems w/ .po files

[Tapan S. P. <ta...@ya...>]

I am having some problems with PO files I am creating in yudit.  Please
see the attached file, where I have localised the problem string to the
Tamil translation for Password.  (Please dont try to read the Tamil, it
is only for testing... ;)

I have changed this string a little and now it works fine, but I am
curious why the original string wasnt working.  When I tried to use it I
would get weird Pango errors telling me I was using invalid UTF-8
strings and other similar errors...

Is Yudit not producing valid UTF-8?  Is this string somehow not valid in
Tamil and that is the problem?

Any ideas appreciated, these kinds of problems would make it hard to
make my po files in Yudit...

I am pretty sure about this. The develeopments of Fontographer 
has been stopped.

I agree on this account. But most of the times, when someone 
is a beginner with OTF, it is difficult to know all the needed 
glyphs in advance. Other thing people do while beginning with 
OTF is to try with a small glyph set first. Of course, these 
are not advisable.

I think FontoGrapher also retains all tables of OpenType. However, I'll
check it once again.

This is really not advisable. Before you start burning OpenType tables into
the font, you should plan and design your glyphs. Iteration may result in
malicious rule and sometimes corrupted tables.

Re: [Indic-computing-users] Akruthi fonts need to be encoded

[Dr. U.B. P. <pav...@vi...>]

Another option is to use the eval copy of Font Creator 
Program (FCP) from www.high-logic.com. The advantage of 
this package compared to Fontographer is that this does not 
knock-off the OpenType tables added by VOLT. Invariably, 
when you create OTF, you need to iterate between a font 
glyph editing package and VOLT. FCP and FontLab are the 
wtoo font glyph editing packages that I know which don't 
knock-off the OTF tables added by VOLT.

I noticed that some thing of this kind may have happened since the
output ttf file from pfaedit was smaller than the original.  I will
have to continue working like this because I have no fontographer in
my office.  Besides I will patiently wait till the technology in the

This minor loss happens only when you saving the font as a

 You dont need to do that with Gtk2 , put ur font in
/etc/fonts/fonts.conf ( for Pango 1.1.x )or /etc/X11/XftConfig

 Below is procedure for using the font with fontconfig & Xft. It will
work even without doing all this stuff if the font is available in the
paths speficied in <dir> options,

 If font selected by font face name or  has been speficied instead of
a generic alias like sans, mono then that font is used, if its not
available default fallback mechanism ( sans, mono etc) will be used .
 If there are two fonts catering to same script, the one in fonts.conf
will be prefered, 
 If there are two or more in fonts.conf for same script then the first
one would be used, 

 You need to install the font  & do settings in /etc/fonts/fonts.conf
(for Xft2) or in
/etc/X11/XftConfig ( for Xft1 ), Add the dir in these config files.

In fonts.conf we need to add our font typeface to the aliases

First install the font ( the usual copy, ttmkfdir, mkfontdir etc ) .
Then add the directory in list below or make sure its under the ones
already below

<!-- Font directory list configured on Sat Aug 31 20:37:33 IST 2002
-->

        <dir>/usr/X11R6/lib/X11/fonts</dir>
        <dir>/usr/share/fonts</dir>
        <dir>~/.fonts</dir>

Add font face  name in aliases

<!--
  Serif faces
 -->
        <alias>
                <family>Times</family>
                <family>Times New Roman</family>
                <family>Nimbus Roman No9 L</family>
                <family>Luxi Serif</family>
                <family>Kochi Mincho</family>
                <family>AR PL SungtiL GB</family>
                <family>AR PL Mingti2L Big5</family>
                <family>Baekmuk Batang</family>
                <family>Subodh1</family>         <-- I added this line
                <default><family>serif</family></default>
        </alias>

There are more options which I have not explored. A similar approach
is taken with XftConfig ( not used with Xft2 )

In each dir where scalable fonts are found, a fonts.cache-1 is created
containing font parameters & what script it caters to.
eg:
"mangal.ttf" 0
"Mangal:style=Regular:slant=0:weight=100:index=0:outline=True:sca
lable=True:charset=  |>^0oyf*?yMW<gJ
!!!!#!2b&R!2b&R!!!B.|>^0nxJnss{~aQ.!!71#   
 !!#0G!~T~}!!!!j      !!#6I!!K?&       !!#AL      !!!W5
:lang=bh|bho|hi|kok|ks|m
r|ne|sa"

To make Gnome use antialiasing & xft modules ( for ttf & opentype
fonts ) of pango ( instead of x modules - bdf fonts )
set
 export GDK_USE_XFT=1
unset
 export GDK_USE_XFT=0

I think I should put this in a howto/tutorial. I have already mailed
this info several times :)

Re: [Indic-computing-users] Raghu, ttmkfdir and Code2000

[Tapan S. P. <ta...@ya...>]

Yup, works.  At least for code2000 which Im using.  I dont see why it
wouldnt work for Raghu also...

I suppose this is an OK solution but it is a bit confusing with all the
difft hooks, Gtk 1.2 vs Gtk 2, no XFT vs XFT 1 vs XFT 2....

How does QT approach all this?  Is it using XFT?

Re: [Indic-computing-users] Raghu, ttmkfdir and Code2000

[Tapan S. P. <ta...@ya...>]

It is in /etx/X11/Xftconfig or in ~/.xftconfig.  You have to set the
font families using stuff like...

match
	any family == "sans"
edit
        family += "raghu";
	size = 11;

or something like that...  Im not sure if this is how it will remain in
Xft2.

Im testing this just now, will let u know how it comes out in 15
minutes... ;)

Having a 0 length kern table should not be considered a bug in the font. I
saw those messages on gtk-i18n list. ttmkfdir uses FreeType and there is an
assumption in FreeType that 0 length table is invalid. They planned to
correct it and I recall that someone suggested patch in FreeType. I don't
know whether they have applied the patch or not.

This can also be used with 16-bit fonts (as you can see name of Raghu
there). And you can even use different styles with different widgets.
Certainly, in this example, it will set the fontset for all widgets; but
you can specify different styles and bind them with different widget
classes. However I have not closely looked at new font settings in Gtk2.
Can you tell us how to set fonts in Gtk2? Is it in xft/ft2 related
directory?

If you open and save font in pfaEdit then there will be some loss in
quality of glyphs because pfaEdit converts Quadratic-Bezier curves into
Cubic-Bezier curves. That's why I prefer FontoGrapher on windows platform.
Use of Free/OpenSource software is always good but unfortunately currently
we don't have very high-quality softwares fot font editing :(

But then input will become a real pain. Can Akruti people release source
code which work for this particular encoding? It will not only save our
time but also make their encoding more popular.

I had a quick look at the fonts and found that some glyphs are missing if
we want to make this font Unicode compliant. So first task should be to
define new glyphset for this font. We can create new glyphs by using
references to older glyphs. It will preserve outlines. Also change in one
place will be reflected automatically at all other places if we use glyph
referencing while creating new glyphs.

 But mangal & other XP fonts work with ttmkfdir from X 4.2 , There is
probably some bug in it. There was a report on gtk-i18n list on  raghu
having a 0 lenth kern table ( I donno if that affects ttmkfdir ).

 This was with 8 bit fonts, with gtk2 we dont need to do all this
stuff, or putting it properly one should not do this stuff, as this
sets the font for all widgets, if your application is to be used for
many languages at same time, setting font explicitly is not good,
unless ur font caters to all languages expected to be used.
 If ur app is still pre gtk2 then certainly this is the proper way to
set font.

[Indic-computing-users] fontset?

[Tapan S. P. <ta...@ya...>]

I am monkeying around i18nizing a Gtk-2 app, and I am finding the only
way to set a font that I am able to view properly is to put an explicit
font-name setting in the .rc file.  I am also finding that the fontset
setting doesnt work, I think Xft doesnt handle it properly...

This causes a big problem because then it means that its hard to specify
more than 1 font for an application, meaning if that font doesnt have
all 
chars u want u are in trouble...  anyone know of any workaround of
getting this to work using fontset or some other less bruteforce
mechanism?  I think the other option is to put some family settings in
.xftconfig....  

The Xft coordination with Gtk / Pango folks could be alot better it
seems...

i just spent the last two days i18n-izing my project.  lots of caveats
and problems that are VERY poorly documented on the web...  Here are
just a list of things I can think of:

- getting your gettext/po architecture and coordinating with
your Makefile structure
- populating and installing po files using some editor
- installing proper fonts
- configuring X and Xft to use those fonts
- configuring your app to use the correct fonts
- setting and using locales, etc.

So far Ive got the thing working and integrated nicely with my build
process, but I have to admit there is a good 20-30% of things I did
above I dont even understand...  It seems that not too many people have
gotten to work on actually localising apps yet so the documentation on
the web is a little sparse...

When I get time Ill write up a quick HOWTO with links about this process
w/ an emphasis on Indic....

Unfortunately, ttmkfdir can't generate proper XLFD name for Unicode encoded
fonts that fall under Indic range. New programs are being written which
will eventually replace ttmkfdir. Meanwhile you can put the following XLFD
name for Raghu in your fonts.scale file:

    raghu.ttf -NCST-Raghindi-medium-r-normal--0-0-0-0-p-0-iso10646-1

Look for files in /etc/gtk (or /etc/gnome) directory. For newer version of
gtk it may be in /etc/gtk-2 directory. Those files are having name
 gtkrc.[locale_name]. For example, gtkrc.hi_IN or gtkrc.ta_IN. You can
specify fontset to be used for a particular locale. Following is an
example:

# This is sample gtkrc file for hi_IN locale
  
style "gtk-default-hi_IN" {
     fontset = 
           "raghu, \
            -misc-fixed-medium-r-normal--15-140-75-75-c-90-iso8859-1" 
}
class "GtkWidget" style "gtk-default-hi_IN"

Hi all,
  I am using Redhat 8.0. I couldnt use the truetype font (our own) there.
  I used the xfstt also. The font is available in xlsfonts, but in the 
  control center, the font is not available.

Re: [Indic-computing-users] Akruthi fonts need to be encoded

[Baiju M <mal...@ya...>]

Now I started working on Malayalam fonts.

If anybody else working on Malayalam, please inform me, so that
we can avoid duplication efforts.

BTW, those who decided to use only *free* softwares for
developing OpenType fonts, use PfaEdit and TTX (Python package
to 
dump TTF to XML http://sf.net/projects/fonttools) and use your
favorite text editor to edit advanced OpenType tables
(GSUB,GPOS,GDEF etc.).

[Indic-computing-users] Akruthi fonts need to be encoded

[Nagarjuna G. <nag...@hb...>]

We started working with the akruthi fonts with a team of volunteers.
With these set of fonts I think the following needs to be done.

1. First the fonts are not encoded for utf-8 input method.  So the
font file should be opened in a editor (pfaedit) and cut paste the
glyphs at the appropriate unicode pages and recreate the fonts.

2. The other alternative is to use the existing encoding which uses
the first 256 characters of the kb, and make a xmodmap file.  May be
we can use both the strategies.

Before we begin converting them to opentype fonts, we wish to make the
fonts work so that the OS begins to support indian languages.  Since 1
and two are not very difficult tasks, please find time to do that.  To
eliminate overlapping let us announce who is doing what in the list so
that we save time.  Our group is now working on the devanagari fonts.
After our experiment succeeds we will inform and uplaod the results.

I also want the experts to inform me if the strategy is not correct.
I am just beginning to understand the technology so I may be wrong in
my decisions.

[Indic-computing-users] Raghu, ttmkfdir and Code2000

[Tapan S. P. <ta...@ya...>]

How come raghu font doesnt work with ttmkfdir?  Is there a workaround to
use this font in X?

For now I am using Code2000, but it doesnt look nearly as nice... ;(  

Are there any good unicode Tamil fonts around?  

My next question is that I am now trying to display Unicode Hindi and
Tamil in my GTK-2 application, but Im not sure how can I have it find
the default fonts for those ta_IN and hi_IN locales?  Does someone have
an example of a gtkrc file that I should put somewhere?
