If we're headed that way, I figured I should double-check.  The RFC
I referenced was later obsoleted by:

http://www.ietf.org/rfc/rfc3986.txt

I haven't been able to find anything more recent.  This newer RFC
doesn't seem to list characters which are *not* part of a URI, so
here are the characters which *are* allowed:

  gen-delims  = ":" / "/" / "?" / "#" / "[" / "]" / "@"

  sub-delims  = "!" / "$" / "&" / "'" / "(" / ")"
                / "*" / "+" / "," / ";" / "="

  unreserved  = ALPHA / DIGIT / "-" / "." / "_" / "~"

I'll read this RFC closely and follow up later today.
