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.
