There have been issues with non-latin1 diacritics and unicode.
http://bugzilla.kernel.org/show_bug.cgi?id=7746
Git 759448f459 `Kernel utf-8 handling'
partly resolved it by adding conversion between diacritics and
unicode. The patch below goes further by just turning diacritics into
unicode, hence providing better future support. The kbd support can be
fetched from
http://bugzilla.kernel.org/attachment.cgi?id=12313
This was tested in all of latin1, latin9, latin2 and unicode with french
and czech dead keys.
Turn the kernel accent_table into unicode, and extend ioctls KDGKBDIACR
and KDSKBDIACR into their equivalents KDGKBDIACRUC and KDSKBDIACR.
New function int conv_uni_to_8bit(u32 uni) for converting unicode into 8bit
_input_. No, we don't want to store the translation, as it is potentially
sparse and large.
