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, combining diaresis) and returns the combined form, if it exists. For example echo e0308 | rune/uconv | rune/compose
