I love that Scheme symbols may have characters other languages disallow.
I can't support not being able to name libraries with the same freedom
as with all other symbols, nor allowing the flaws of prevalent OSs to
determine libraries' names, nor asking that library-name symbols like
'and-let* be renamed like 'and-let-star.  We have a different situation
than C.

The upcoming revision is explicit that it is for unixoids and Windoze.
When they finally die, so will this SRFI.  Scheme systems implementing
this SRFI may still do something else for other OSs, which may be
addressed by other SRFIs.  

The social solution has the problem that people would be guessing what
characters they shouldn't use, leading back to the current situation of
trying to get everyone to be consistent.  Unfortunately, we can't remove
the OS restrictions which make the additional feature of encoding
necessary.  Fortunately, the encoding is simple and we can flush it and
this SRFI entirely in the future when better data storage systems are
prevalent.  We need something which supports proper Schemely names until
then.
