Support for substitute fonts / unicode strings? #4

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Do you plan to support font substitution, so that when a font doesn't supply a 
needed glyph, it is loaded from another automatically? That would be nice for 
general unicode support, since very few fonts support the full unicode range. 
You already seem to use fontconfig, so that shouldn't introduce new 
dependencies.

I would need the name of the default font to be used on every platform and I'm 
not sure of the result since the look & feel would be quite different.

I'm not sure why you'd need the default font. What I meant was to take a 
substitute font from fontconfig, when the given font doesn't have the needed 
glyph. Or maybe, since fontconfig might only be set up properly on Linux 
systems, to be able to manually construct font sets from which substitute fonts 
are taken.

Ok, but I'mnot sure how to find a substitute font from fontconfig. Let's say I 
requested 'Arial' and see that I miss some glyphs, what is the font to be 
requested to get the missing glyph ?

I have to admit that I don't know how fontconfig works on the developer side. 
As a user, I can e.g. put

        <alias>
                <family>PT Serif</family>
                <prefer>
                        <family>PT Serif</family>
                        <family>Sazanami Mincho</family>
                </prefer>
        </alias>

in my configuration, then when selecting PT Serif in an application and showing 
Japanese text, Sazanami Mincho will be used.

Well, me neither and it would request a lot of work I fear.
If someone comes with a nice solution, I will include it.
