[XeTeX] Fonts partially available in XeTeX but 'fully' available in Inkscape

[Pander]

Hi all,

When I use a font like Titr or Homa in XeTeX, it will only print the
numbers 0123456789 but no glyphs for ABC... However, in Inkscape it does
have glyphs for ABC.

Are these provided via font substitution according to the Panose
classification or is something else going on becaue they don't look like
your standard FreeSans or FreeSerif?

Thanks,

Pander
