Re: [PATCH] Completed unaccent dictionary with many missing characters

That'd leave just DEGREE CELSIUS and DEGREE FAHRENHEIT.  Not sure how
to kill those last two special cases -- they should be directly
replaced by their decomposition.

[1] https://unicode-org.atlassian.net/browse/CLDR-11383

I patch v3 support for cirilic is added.
Special character function has been purged.
Added support for category: So - Other Symbol. This category include
characters from special_cases().

I think that we'd better split v3 into more patches to keep each
improvement isolated.  The addition of cyrillic characters in the
range of letters and the removal of the sound copyright from the
special cases can be done on their own, before considering the
original case tackled by this thread.
