             Summary: StringPrep use newer Unicode then StringPrep RFC 3454
                 Key: ELY-48
                 URL: https://issues.jboss.org/browse/ELY-48
             Project: WildFly Elytron
          Issue Type: Bug
      Security Level: Public (Everyone can see)
            Reporter: Jan Kalina
            Assignee: Darran Lofthouse
            Priority: Minor


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 that using of newer Unicode can be tolerated, but it can depend on using of this profile.
