  The value is always an Unicode value.

  "Loading Arial" means creating new TTCFont?  TTCFont doesn't cover
beyond 256 chars.  TTCFontSet does something (see HostFont
class>>initForSubtitles), but needs a bit work-out.

  Basically,

TTCFontReader encodingTag: Latin1Environment leadingChar.
TTCFontSet newTextStyleFromTTFile: 'C:\WINDOWS\Fonts\arial.TTF'.

should create right TTCFontSet structure and the character with 16r107
value with 0 as encodingTag should be displayed with the font.

  (Latin1Environment meaning the language the latin1 char set
supports, or in this case it means the default language environment.
The word latin1 in it doesn't specify the character range.)

  Sorry for inconvenience,
