Text as understood by a user of a text editor does not necessarily
correspond to strings as understood by a programmer.

But indeed, it's foreseeable that Guile would support such things in its
native string data type eventually, when explicitly requested.  ISTR
this was mentioned before, by Guile developers themselves.  Then Elisp
and Guile strings would not need to be different data types anymore.

Though that doesn't seem to be an absolute requirement for letting
libguile compile Elisp, since it can just treat Elisp strings as a
separate data type, as GuileEmacs currently does.
