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.
