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
       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.
