[cdesktopenv-devel] Is dtterm supposed to be unicode-aware?

[Eugene D. <du...@gm...>]

Hi Tomasz,

dtterm (and rest of CDE apps) in fact do work with unicode characters,
but there are lots of rough edges.

First of all, they do not seem to work with  ISO10646-1 encoded XLFD fonts,
but require compound font sets , that is each codepage must be
provided by separate 8-bit encoded font.

Another problem is that dtterm for some reason does not seem use such font
sets
properly when they are given from command line (or at least I never manged
to get it to work).

These command lines  should work:

dtterm -fn 'some font-iso8859-1,some font-iso8859-2,some font-iso8859-3...'

or

dtterm -fn 'some font-iso8859-*'

but I always got something like your second screenshot.

However, it does work when CDE is globally configured to
use UTF-8, that is by setting the LC_ALL enviroment variable and
adding /usr/dt/config/xfonts/en_US.UTF-8/ to font path.
Dtlogin does it for you when you choose en_US.UTF-8 as session language.

If it does not work for you, check
the  /usr/dt/config/xfonts/en_US.UTF-8/fonts.alias file.
It must define CDE aliases to fonts that exist on your system. The provided
file assumes that
you have ms core fonts installed and available for X applications as XLFD
fonts.

In case you want hebrew and arabic (symbols only, RTL is unsupported by
underlying Motif library)
you may have to add entries for them
to /usr/share/X11/locale/en_US.UTF-8/XLC_LOCALE.

To give you some encouragement I attach my dtterm screenshot :-)

Good luck,
Eugene
