'\"	and indent is equivalent to second arg of .IP (shouldn't ever be
'\"	needed;  use .AS below instead)
'\"
'\" .AS ?type? ?name?

.SH DESCRIPTION
.PP
The first three routines convert the case of individual Unicode characters:
.PP
If \fIch\fR represents a lower-case character,
\fBTcl_UniCharToUpper\fR returns the corresponding upper-case
character.  If no upper-case character is defined, it returns the
character unchanged.
.PP
If \fIch\fR represents an upper-case character,
\fBTcl_UniCharToLower\fR returns the corresponding lower-case
character.  If no lower-case character is defined, it returns the
character unchanged.
.PP
If \fIch\fR represents a lower-case character,
\fBTcl_UniCharToTitle\fR returns the corresponding title-case
character.  If no title-case character is defined, it returns the
corresponding upper-case character.  If no upper-case character is
defined, it returns the character unchanged.  Title-case is defined
for a small number of characters that have a different appearance when
they are at the beginning of a capitalized word.
.PP
The next three routines convert the case of UTF-8 strings in place in
memory:
.PP
\fBTcl_UtfToUpper\fR changes every UTF-8 character in \fIstr\fR to
upper-case.  Because changing the case of a character may change its
size, the byte offset of each character in the resulting string may
differ from its original location.  \fBTcl_UtfToUpper\fR writes a null
byte at the end of the converted string.  \fBTcl_UtfToUpper\fR returns
the new length of the string in bytes.  This new length is guaranteed
to be no longer than the original string length.
.PP
\fBTcl_UtfToLower\fR is the same as \fBTcl_UtfToUpper\fR except it
turns each character in the string into its lower-case equivalent.
.PP
\fBTcl_UtfToTitle\fR is the same as \fBTcl_UtfToUpper\fR except it
turns the first character in the string into its title-case equivalent
and all following characters into their lower-case equivalents.

.SH BUGS
.PP
At this time, the case conversions are only defined for the ISO8859-1
characters.  Unicode characters above 0x00ff are not modified by these
routines.

278	.SH DESCRIPTION
279	.PP
280	The first three routines convert the case of individual Unicode characters:
281	.PP
282	If \fIch\fR represents a lower-case character,
283	\fBTcl_UniCharToUpper\fR returns the corresponding upper-case
284	character. If no upper-case character is defined, it returns the
285	character unchanged.
286	.PP
287	If \fIch\fR represents an upper-case character,
288	\fBTcl_UniCharToLower\fR returns the corresponding lower-case
289	character. If no lower-case character is defined, it returns the
290	character unchanged.
291	.PP
292	If \fIch\fR represents a lower-case character,
293	\fBTcl_UniCharToTitle\fR returns the corresponding title-case
294	character. If no title-case character is defined, it returns the
295	corresponding upper-case character. If no upper-case character is
296	defined, it returns the character unchanged. Title-case is defined
297	for a small number of characters that have a different appearance when
298	they are at the beginning of a capitalized word.
299	.PP
300	The next three routines convert the case of UTF-8 strings in place in
301	memory:
302	.PP
303	\fBTcl_UtfToUpper\fR changes every UTF-8 character in \fIstr\fR to
304	upper-case. Because changing the case of a character may change its
305	size, the byte offset of each character in the resulting string may
306	differ from its original location. \fBTcl_UtfToUpper\fR writes a null
307	byte at the end of the converted string. \fBTcl_UtfToUpper\fR returns
308	the new length of the string in bytes. This new length is guaranteed
309	to be no longer than the original string length.
