i still don't understand why can't it work ithout first/next char functions.
you render the char when it first appears on teh screen, right?
so you can request glyph for the given unicode, and if it fails then no such
char, otherwise you got it.

yes, and sorry for that. i promised i'll look at it this weekend but was
busy with realaudio hacking and other things...
just tested this patch and still sig11's as soon as it wants to display any

imho copying it to the common data dir (along with codecs.conf) could be fine
anyway it's small compared to mplayer size so it doesn't matter :)
