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 associ-
       ated with the various routines.

       Note:  A  Tcl_UniChar  is a Unicode character represented as an unsigned, fixed-size quan-
       tity.

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 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 alphanumeric or	a  connector  punctuation
       mark.

KEYWORDS
       unicode, classification
