Is Python supposed to support POSIX "equivalence classes"? I tried
the following in Py2 and Py3:
>>> re.sub('[[=a=]]', 'A', 'aáàãâä', re.U)
'aáàãâä'
which suggests that it doesn't (I would have expected "AAAAAA" as the
result).
Is there a way to get this behavior?
I found that perl knows about them but treats them as an exception
for now[1]. Supposedly GNU awk (and other GNU POSIXish tools)
recognize character classes, as does vim.
Thanks,
-tkc
