RUNECLASS(2) RUNECLASS(2)
NAME
runeclass, runecompose - Unicode character equivalence
SYNOPSIS
#include <u.h>
#include <libc.h>
Rune *runeclass(Rune r)
int runecompose(Rune base, Rune combiner)
DESCRIPTION
These routines use codepoint properties from the Unicode
standard to combine and determine sets of characters with
the same base character. The set of codepoints with the
same base codepoint are a generalization of the equivilence
between various cases such as title, lower an upper:
runeclass returns this set. Likewise, runecompose takes a
base codepoint and a combining codepoint (e.g. u+0308, com-
bining diaresis) and returns the combined form, if it
exists. For example
echo e0308 | rune/uconv | rune/compose
