Also remember that Guile uses the system C library regex routines. And
is using C strings, not Guile strings.

Subject: bug#57507: Regular expression matching depends on locale
encoding
Regular expressions do funky things with Unicode if a
non-Unicode-aware
locale is set. Yet, they're purely string operations, so I don't
think
it's expected that they depend on the locale encoding.
