From b8b885daf7b6b368c8ad7a31dfc89b44f993d21b Mon Sep 17 00:00:00 2001 From: Samuel Thibault Date: Mon, 21 Feb 2011 17:27:38 +0100 Subject: Match braille patterns with compose tree Braille patterns should also be usable in Compose. This combines the implementation of braille chords and compose tree: only emit the braille pattern if it can not be found in the compose tree, if any.
