Re: [Bug-XBoard] [bug #33241] xboard quits with "Unable to create font s

OK, I found out what's going on. Xaw is internationalized and supports utf8, but on each widget we need to set the international resource to True, AND we need to set the fontSet resource to the fontset we want to use. When international is True, the widget's font resource is ignored and the fontSet resource is used instead.

The current FindFont procedure (when ENABLE_NLS is defined) works by finding a fontset, then pulling a single font out of it and returning that for use with all the older code in xboard.c that was there prior to internationalization and wants to deal with fonts instead of fontsets. It looks like we need to change FindFont to just return the fontset, then change the rest of the code to set fontSet resources using that value instead of setting font resources.  That looks like it will be a fair amount of work to carry through fully. Maybe it's best to nuke all the old code in the process instead of trying to carry it around and make it still work if compiling without ENABLE_NLS defined.

As a partial mock-up, though, you can see the fontSet resource at work just by setting it from the command line:

LC_ALL=de_DE.utf8 ./xboard -ncp -size medium -xrm '*international: True' -debug  -xrm '*whiteTime*fontSet: -adobe-helvetica-bold-r-normal--34-*-*-*-*-*-*-*' -xrm '*blackTime*fontSet: -adobe-helvetica-bold-r-normal--34-*-*-*-*-*-*-*' -xrm '*fontSet: -adobe-helvetica-medium-r-normal--14-*-*-*-*-*-*-*'

That only sets the clock font and the default font, not the coord font, but gives you the idea.

After some more random googling and flailing, I have learned that setting the resource "*international: True" in Xaw widgets makes them do something more nearly correct.  Try this:

env LANG=de_DE.utf8 xboard -xrm '*international: True'

When I do that, I get correct umlauts and the ß character in Weiß (=White). But I don't get the right font -- it looks like all the characters are coming from the "fixed" font; they are all small and fixed-width.

does anyone know of any other Xaw program that uses gettext? Perhaps we
can just check their code and see how they do it ;) I can't think of any
right now though, but will search a bit once I have some time on my hands...
