Check character glyph index before using cached Font

CJK script use 3 fonts (chiniese. japanese, korean),
  (tizen TV has, BreezeSansChinese-Regular.ttf, BreezeSansJapanese-Regular.ttf, BreezeSansKorean-Regular.ttf)

Some CJK characters may not be included in these three fonts.
In this case, it need to search fallback font again.
