[MPlayer-users] Incorrect font selection in libass (once again)

[Vladimir Mosgalin]

Hi everybody.

This question is primary for Evgeniy, as I suspect. I have a mkv file
with embedded fonts, and libass fails to choose one of them, rolling
back to Sans. I wonder if subtitles should be fixed or some solution can
be applied to libass to pick up correct font.

Running mplayer -v produces output:

mkv file has attachment with ID 1217773493, called RUBTTS__.TTF. I
extracted it. Here's "ftdump RUBTTS__.TTF" output:

Also there's another problem with this file, resulting in messages like

The offending like in .ass are

Words "Summer" and "Break Special" are written with this (cool-looking)
font, but "Home Inspections" isn't. Yeah I notice the double \fn ;)
