Handle glyphs from multiple fonts

Previous ticket about this problem is #5829 (closed). As suggested in commentary 11 in #5829 (closed) I fill separate ticket. For more information please read previous discussion.

1. Work with fonts like Droid Sans, where both of Cyrillic and Japanese glyphs is available in fonts set, but in different font files (for example cyrillic available in Droid Sans and Japanese glyphs in Droid Sans Japanese) is unimplemented in VLC. Expected behavior: if user select Droid Sans in settings VLC take latin or cyrillic from Droid Sans and Japanese glyphs from Droid Sans Japanese. For example Libre Office work in this way (AFAIK).
2. Fallback for glyphs that is not available in selected font is unimplemented in VLC. Expected behavior: VLC use fallback font when it's not available in selected font instead of displaying rectangles. There also shall be option for disabling this behavior.

changed title from VLC doesn't handle glyphs that is not available in selected font properly to Handle glyphs from multiple fonts
