.BI "int tickit_utf8_mbswidth(const char *" str );
.sp
.BI "int tickit_utf8_byte2col(const char *" str ", size_t " byte );
.BI "size_t tickit_utf8_col2byte(const char *" str ", "int " col );

.SH DESCRIPTION
These functions are a set of shortcut wrappers around \fBtickit_utf8_count\fP(3) for performing a single simple counting operation on a given string. When performing multiple operations on a given string, it is more efficient to use \fBtickit_utf8_count\fP() directly.
.PP
\fBtickit_utf8_mbswidth\fP() returns the number of columns wide the given Unicode string consumes.
.PP
\fBtickit_utf8_byte2col\fP() and \fBtickit_utf8_col2byte\fP() convert between byte and column indexes within a given string; returning one when given the other.
.SH "RETURN VALUE"
\fBtickit_utf8_mbswidth\fP() and \fBtickit_utf8_byte2col\fP() return an integer column count. \fBtickit_utf8_col2byte\fP() returns an integer byte count.
