Sorry, according to the TT spec, windows TT fonts cannot have glyphs
in the 0x00 to 0x1F positions. Thus, 256 character fonts are
prohibited. If you try to put glyphs below 0x20, Windows will
interpret the first non-blank glyph as 0x20.

Moreover, the spec also prohibits Windows TT fonts from encoding
characters that don't correspond to UNICODE characters, such as
ligatures (like the fi and fl ligs in the Standard Type1 Encoding
Vector).  Why Microsoft confused a _character_ encoding scheme
(UNICODE) with glyph encoding, I'm sure I don't know.  A Macintosh TT
font _can_ have ligatures, but Microsoft forbids the Windows version
from having those glyphs.
