Now that many of the external programs to which TeXmacs interfaces are
able to use utf-8 it would be good if a new version of the TeXmacs
Scheme data format (say, scheme-utf-8 ) could be defined that
interpreted utf-8 characters as TeXmacs symbols. Then adding utf-8
support to any interface that currently uses scheme could be almost as
simple as writing "scheme-utf-8:" instead of "scheme:" in the
generated output.

In any case I now have a patch to the texmacs package in FriCAS that
does the utf-8 to Cork conversion. I have attached a draft FriCAS
patch, the modified fricas-input plugin and an example document (also
in PDF format).

More comments welcome!  If/when there are no objections or suggestions
I will clean it up and submit a final version.

Bill Page.
