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  associ-
       ated  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  alphanu-
       meric Unicode character.

       Tcl_UniCharIsAlpha tests if the character is an alphabetic
       Unicode character.

       Tcl_UniCharIsControl tests if the character is  a  Unicode
       control character.

       Tcl_UniCharIsDigit  tests  if  the  character is a numeric
       Unicode character.

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

       Tcl_UniCharIsLower  tests  if the character is a lowercase
       Unicode character.

       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 character.

       Tcl_UniCharIsUpper  tests if the character is an uppercase
       Unicode character.

       Tcl_UniCharIsWordChar tests if the character  is  alphanu-
       meric or a connector punctuation mark.


KEYWORDS
