The Tcl_UniChar to be examined.

.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.
