From 46b78113b22428e6f8540193fcf0e00591dbd724 Mon Sep 17 00:00:00 2001 From: Konstantin Ritt Date: Thu, 26 Apr 2012 19:29:08 +0300 Subject: [PATCH] add support for non-BMP ligatures > http://www.unicode.org/versions/Unicode5.2.0/ D. Character Additions: There are three new characters in the newly-encoded Kaithi script that will require changes in implementations which make hard-coded assumptions about composition during normalization. Most new characters added to the standard with decompositions cannot be generated by the operations toNFC() or toNFKC), but these three can. Implementers should check their code carefully to ensure that it handles these three characters correctly.
