DESCRIPTION

       All of the routines described examine Tcl_UniChars 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 Tcl_UniChar is a Unicode character represented as an  unsigned,
       fixed-size quantity.

CHARACTER CLASSES

       Tcl_UniCharIsAlnum  tests  if  the character is an alphanumeric Unicode
       character.

       Tcl_UniCharIsAlpha tests if the  character  is  an  alphabetic  Unicode
       character.

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

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

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

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

       Tcl_UniCharIsPrint tests if the character is a Unicode print character.

       Tcl_UniCharIsPunct tests if the  character  is  a  Unicode  punctuation
       character.

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

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

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