There is no hook for extending the string syntax, so you'll need a new
reader macro for strings.  If you want all of mzscheme's escapes, then
the tedious part in this will be all the numeric escapes (octal and
hex).  So depending on the problem you're trying to solve, it might be
easier to define a new kind of escape, or maybe use something like the
scribble syntax (http://docs.plt-scheme.org/scribble/reader.html).
