--- Comment #2 from Michael Stefaniuc mstefani@redhat.com 2009-03-18 17:24:21 --- As the mappings are generated from the Microsoft Bestfit Mappings on unicode.org I have searched around to see how those get updated. It looks like Microsoft won't do it if the below two links is to be trusted: http://osdir.com/ml/ietf.charsets/2006-10/msg00076.html http://blogs.msdn.com/shawnste/archive/2007/09/24/are-we-going-to-update-or-...
So it looks like we would have to provide our own bestfit extensions iff we want to fix this problem.
