 Summary of the bug:
 glyphs is broken at drawtext filter
 when a sentence is mixed other character set
 (ex. english+korean)
 I ran ffmpeg on windows 10

 However I found the solution at libass library
 You have to set the substitution font by FcConfigSubstitute function when
 ffmpeg sets font on drawtext filter.

 How to reproduce:
 {{{
 % ffplay -i anything -vf "[in]drawtext=font='Arial':text='ffmpeg 에프에프
 엠펙'"
 ffmpeg version 4.3
 built on ... msys2
 }}}
 Patches should be submitted to the ffmpeg-devel mailing list and not this
 bug tracker.
