True - in LaTeX, \backslash only exists in math-mode. Why copy this
strangeness to TeXmacs? I think all the ASCII characters should exists
in text-mode as well. I mean, all the characters $, ^, _, # and so on
exists in text-mode. Why not backslash?

Of course, when exporting to LaTeX, the \backslash strangeness has to be
taken care of, just as I did below.

Why that? Except for \backslash, TeXmacs displays all characters
correctly in text-mode. LaTeX also knows how to handle them in text-mode
if they are escaped correctly. It is just the spacing that is done
incorrectly at export time, as well as the \backslash that has to be
handled as special case in LaTeX export.
