+.SH DESCRIPTION
+.PP
+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.
+.PP
+Note: A Tcl_UniChar is a Unicode character represented as an unsigned,
+fixed-size quantity.
+
+.SH "CHARACTER CLASSES"
+.PP
+\fBTcl_UniCharIsAlnum\fR tests if the character is an alphanumeric Unicode character.
+.PP
+\fBTcl_UniCharIsAlpha\fR tests if the character is an alphabetic Unicode character.
+.PP
+\fBTcl_UniCharIsControl\fR tests if the character is a Unicode control character.
+.PP
+\fBTcl_UniCharIsDigit\fR tests if the character is a numeric Unicode character.
+.PP
+\fBTcl_UniCharIsGraph\fR tests if the character is any Unicode print character except space.
+.PP
+\fBTcl_UniCharIsLower\fR tests if the character is a lowercase Unicode character.
+.PP
+\fBTcl_UniCharIsPrint\fR tests if the character is a Unicode print character.
+.PP
+\fBTcl_UniCharIsPunct\fR tests if the character is a Unicode punctuation character.
+.PP
+\fBTcl_UniCharIsSpace\fR tests if the character is a whitespace Unicode character.
+.PP
