Description
RFC 3454 (StringPrep) define table of unassigned codepoints by Unicode 3.2:
http://tools.ietf.org/html/rfc3454#section-7
But StringPrep implementation use java.lang.Character.getType(), which use newer Unicode, where same of defined unassigned codes are already assigned.
Examples: codepoint 0x0221, 0x0234 and 0x02EF
All are defined in RFC as unassigned but in Unicode 4.0.0 they are assigned:
http://www.fileformat.info/info/unicode/char/02EF/index.htm
I think using of newer Unicode can be tolerated, but it can depend on purpose of this profile of encode function.
