Oh yes! Try using a symbol font like
"-adobe-symbol-medium-r-normal--14-140-75-75-p-85-adobe-fontspecific" and scanning
GetTextExtentPoint calls through it from FirstChar to LastChar. WordPerfect
likes to do this every time the user selects a new font and wine crashes in
X11DRV_GetTextExtentPoint on a pointer lookup of the "translated" character encoding
determined by MultiByteToWideChar.
I figure the following fixme is a symptom of my problem:
fixme:string:MultiByteToWideChar MB_COMPOSITE not supported
and here is the code in graphics/x11drv/text.c that is abused by the "mapping":
413 x += pfo->fs->per_char ?
414 pfo->fs->per_char[str[i] - pfo->fs->min_char_or_byte2].attributes :
415 pfo->fs->min_bounds.attributes;

Same here. Do we properly track if the X font says its encoding is fontspecific?
(this is new stuff for me..)
