[Openmcl-devel] Unicode issues, esp security

[Dan Weinreb]

Luis,

 From two Unicode experts I have consulted come
the following comments:

See:

http://www.unicode.org/reports/tr36/

Cases like this, in which an illegal sequence is explicitly
transformed into another illegal sequence, would meet with a lot of
resistance from folks who care about security.

It's important not to do anything outside the definition.  Your
objection to CODE-CHAR returning NIL is incompatible with the Unicode
concept of "Noncharacters".  See the Unicode report section 16.7.
