It's in git HEAD if you want to have a look.

Yep.  MSF is broken with respect to non-printing sequences and also,
as it turns out, with multibyte UTF-8 characters.  I'm not sure how
widely MSF is used, so this may not be fixed for a while.  Non-printing
sequences will also mess up "remind -c" output; the man page in git HEAD
notes this and provides a recommendation.

You can override a substitution sequence.  For example, if you find you
never use "%7" in your files, you can simply redefine it:

FSET subst_7(a, d, t) timespan()

and "%7" will now magically be equivalent to [timespan()]
See RUN-TIME MODIFICATION OF THE SUBSTITUTION FILTER in the Remind man
page.
