The strings i need to encode are Ruby error messages. I can't say a 
priori which format they will have,
because in some "gems" programmers may define their own exception messages.
For this reason i would prefer to stay far from LaTeX, it has too many 
special characters.
... but, I would need to do some experiments to be sure, at the moment 
this is just my impression.

Umm, let's stay in you example:
This code works:

print 'command:(insert "Scheme says there is an Error")'

My little problem is, how can i tell to TeXmacs that i want that text in 
"red",
using Scheme ? I can't figure what the way to express 
"with|color|red|"foobar"
in Scheme.

For example, try to run Shift+Meta+X (insert "foo"), then try to do the same
thing, but inserting red text. I can't see how.

There is not problem with the encoding, i can play whatever magic
on the string before sending it to TeXmacs.

bye
