DESCRIPTION
       All of the routines described examine Unicode characters	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.

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.

       unicode,	classification
