As far as Kannada is considered, tere is a standard. There is also a free Kannada script software (for Windows) available for FREE download at http://www.bangaloreit.com/html/education/Nudi.html. The s/w includes the standard font (glyph set). For OpenType font, we need more glyphs. There is no need of any font glyph set standard for OpenType font. It is the job of the rendering engine (Uniscribe on Windows XP) to display the font properly. -Pavanaja ----------------------------------------------------- Dr. U.B.

I believe that the main reason why it doesn't support it yet is that none of its current users felt any real need for it. I am sure that commercial font editors are more advanced, but then again, their support teams don't reply to bug reports in the matter of minutes, either... :) > > As a first question, I would like to ask whether there is any > > agreement on the sets of ligatures needed to render particular Indic > > scripts, > As far as Kannada is considered, tere is a standard.

What I meant by an agreed set of required ligatures needs not necessarily be an official standard. But on the other hand, I believe that newspapers and textbooks are printed in all major Indian languages, so a century(-ies) ago, well before any computers, typesetters had to make such lists. I would guess that printing scholarly publications, poetry etc. might require a richer set of glyphs, but nevertheless, I would like to have some goal... On the Uniscribe engine... I have been reading the Microsoft Typography pages, and wasn't smart enough to guess whether Uniscribe simply substitutes the right ligature for the given sequence of characters (using the GSUB table?), or has some smart way of actually *creating* the needed glyphs on-the-fly. You seem to have some first-hand experience with it, perhaps you could help me?

The Kannada OpenType font Tunga that ships with XP has 407 glyphs which is more than enough for printing almost any book in Kannada. In the OpenType font that I am making, I have knocked off some glyphs from this set. Some publishers ask for some special glyphs for printing Sanskrit scriptures in Kannada, music notations, etc. In OpenType font we can add these extra glyphs in the Private Use Area of Unicode. To get these glyphs in the text that we type, we will have to send their respective Unicode values. In OfficeXP this is done by typing the Unicode value and hitting Alt-X. > On the Uniscribe engine...

You seem to have some > first-hand experience with it, perhaps you could help me? Uniscribe renders the OpenType font. The logic for substitution and positioning of the glyphs is supplied by the font. Uniscribe CAN NOT create any glyph on-the-fly. Uniscribe works only on Windows2000 and XP. It does not work on Windows 95/98/ME. What we need is a public domain OpenType font rendering engine for Indic scripts for all platforms, especially for Linux. Indix from NCST is supposed to be one. I have no experience on that. Anyone has? Regards, Pavanaja ----------------------------------------------------- Dr. U.B.

I have no experience on that. > Anyone has? Yes, I have ;-). IndiX has its own Indic Script Shaping engine. It has functions for Syllable breaking, Reordering, etc. Logic for turning ON/OFF script features is also inside the Indic library. For parsing tables of Opentype font, it uses FreeType library.
