Re: [g-i] fonts: a few thoughts

[Attilio Fiandrotti <fiandro@tiscalinet.it>]

Hi

As you may ahve read yesterday [1], now it's possible again building g-i 
ISO images that are based on the latest GTKDFB 2.8.10 libraries instead 
of the old 2.0.9 ones.
One nice thing is that now it's possible changing at runtime the theming 
of the GTK frontend (fonts, colours and graphics of the widgets ) simply 
by checking, at every gtk_initialize() and gtk_go() call, if the 
/etc/gtk-2.0/gtkrc theme file file has changed or not via a 
gtk_rc_reparse_all() call.
In the case the gtkrc file has not changed, no additional oprations are 
make so overhead is non-existing.
Now, this reminds me of this old discussion that was started on this ML 
some months ago about handling of UTF glyph have to get different 
rendering in different languages.
Hidetaka posted some time ago the above localechooser patch that takes 
care of setting correct fonts for chinese, japanese and korean languages.
Davide and me would like to know if the patch for ja, zh and ko is still 
needed or if oriental fonts look correct now.
Also, Davide told me a very similar problem was found with Persian and 
Arabic languages: is this still true?

ciao

Attilio
