Feature suggestion: Different fonts for different input methods

[Gerrit Sangel-2]

Hello,

I am using several input methods for scim, mostly Japanese but also Chinese
traditional and Chinese simplified and sometimes Korean.

If I choose a Japanese font for the character selection, I don’t see the
simplified chinese characters, because they are not in the font. So I
switched to Code2000, because it more or less has everything in it... The
problem now is that code2000 is really ugly :(

What I think would be really great, if one could specifiy individual fonts for
each input method in the global configuration menu. E.g. for Scim-Anthy, I
would choose IPA Mincho, for Scim-Pinyin some Chinese font, for Scim-Hangeul
some Korean font and for maybe Cangjie some font with traditional glyphs in
it.

Would this maybe be possible and someone also likes this? I guess, this would
be really really great.

Gerrit

Your idea sounds nice, but I think the problem is at the application
rendering level: scim does not have any control over the fonts used to
render committed text in applications, so I don't think there is an easy
solution to this problem currently.  In the long term to achieve this it
would require enhancements to gtk/pango etc to handle unihan issues
better, but without storing some language context it is quite hard I guess.

At least, m17n-lib input methods return the information
about language, and as far as I know, gtk/pango handles
language attribute of a text well.  So, the only change we
need is to make scim and gtk-im-module correctly hand over
the language information.

But I can choose the font which Scim (or in my case Skim) uses globally for
the popup menu? Right now, I’ve set Code2000, because it has more or less
everything in it, but imho this isn’t the best solution.

But if Scim (or is this a Skim issue?) can do this globally, why not for every
input method?

What desktop are you using?  KDE?

GNOME (ie gtk and pango) can use several fonts in the same buffer no
problem, but qt has problems in this regard.  It is not SCIM issue if I
am understanding you correctly.

Yes, I’m using KDE.

I’m not really sure about QT, but I’ve done a little application myself and it
is absolutely no problem in QT4 to change the fonts in a QLabel with some
html markup.

If you do it like

“This is in font 1 <span font-family="font2">and this in font 2</span>”

or something like this, it works.

But for this issue, I don’t think scim or skim would need different buffers. I
think, if the user could specify the font for each input method, it would be
nothing else than switching the font globally before changing the input
method. Just a little bit more convenient :)
