I tried to fix it in r62269 and backported. The fix assumes there is no font with non-ascii characters which might not be always true, I don't know.

I'm not sure I understand: your fix assumes that there is no font used in GRASS with non-ascii characters, or that the issue that Helmut reports is due to the use of a font without non-ascii characters ?

Sorry for the confusing sentence. The limitation of the fix is that the font name can't have any non-ascii characters.

I tested it with latest build, it works.
