[pstricks] Including new fonts in LaTeX (OT?)

[tiM]

I guess it's the wrong place to ask, so please just ignore this mail if it
shouldn't be posted here!

The reason i post it here because i think for those who know how to do it,
it should be easy but i can't find working solutions on the web. I'm trying
to include characters from a specific font in latex (if easier/necessary via
pstricks). I have these fonts in .otf and .svg. Anyone who knows how to do
that?

Gr. tiM
