The attached patch changes Tools/unicode/makeunicodedata.py to create a list of
names and codepoints taken from
http://www.unicode.org/Public/6.0.0/ucd/NameAliases.txt and adds it to
Modules/unicodename_db.h.
During the lookup the _getcode function at Modules/unicodedata.c:1055 loops
over the 11 aliases and checks if any of those match.
The patch also includes tests for both unicodedata.lookup and \N{}.
I'm not sure this is the best way to implement this, and someone will probably
want to review and tweak both the approach and the C code, but it works fine:
>>> "\N{LATIN CAPITAL LETTER GHA}"
'Ƣ'
>>> import unicodedata
>>> unicodedata.lookup("LATIN CAPITAL LETTER GHA")
'Ƣ'
>>> "\N{LATIN CAPITAL LETTER OI}"
'Ƣ'
>>> unicodedata.lookup("LATIN CAPITAL LETTER OI")
'Ƣ'
The patch doesn't include changes for NamedSequences.txt.
