       int          ch                 (in)      The  TclUniChar  to be exam-

DESCRIPTION
       All of the routines described examine TclUniChars and return a boolean
       value.  A non-zero return value means that the character does belong to
       the character class associated with the called  routine.  The  rest  of
       this  document just describes the character classes associated with the
       various routines.

       Note: A TclUniChar is a Unicode character represented as an  unsigned,
       fixed-size quantity.


CCHHAARRAACCTTEERR CCLLAASSSSEESS
       TTccllUUnniiCChhaarrIIssAAllnnuumm  tests  if  the character is an alphanumeric Unicode
       character.

       TTccllUUnniiCChhaarrIIssAAllpphhaa tests if the  character  is  an  alphabetic  Unicode
       character.

       TTccllUUnniiCChhaarrIIssCCoonnttrrooll  tests if the character is a Unicode control char-
       acter.

       TTccllUUnniiCChhaarrIIssDDiiggiitt tests if the character is a numeric Unicode  charac-
       ter.

       TTccllUUnniiCChhaarrIIssGGrraapphh  tests if the character is any Unicode print charac-
       ter except space.

       TTccllUUnniiCChhaarrIIssLLoowweerr tests if the character is a lowercase Unicode  char-
       acter.

       TTccllUUnniiCChhaarrIIssPPrriinntt tests if the character is a Unicode print character.

       TTccllUUnniiCChhaarrIIssPPuunncctt tests if the  character  is  a  Unicode  punctuation
       character.

       TTccllUUnniiCChhaarrIIssSSppaaccee tests if the character is a whitespace Unicode char-
       acter.

       TTccllUUnniiCChhaarrIIssUUppppeerr tests if the character is an uppercase Unicode char-
       acter.

       TTccllUUnniiCChhaarrIIssWWoorrddCChhaarr  tests if the character is alphanumeric or a con-
       nector punctuation mark.
