[XeTeX] accessing fonts from TeX tree and glyphs without Unicode slot

[Mojca Miklavec]

Hello,

I have two questions about fonts in XeTeX:

- Is it possible to use OpenType fonts that reside in TeX tree instead
of having to install them to the system first? (There are dozens of
Latin Modern fonts for example that I never use otherwise.)

- How can I access the glyphs which are not part of Unicode (I know
the name of the glyphs, but that letters don't exist in Unicode)?
(OpenType)

Thanks,
    Mojca
