"""Fixer that changes unicode to str and unichr to chr, but -- unlike the
|
|
lib2to3 fix_unicode.py fixer, does not change u"..." into "...".
|
|
|
|
The reason is that Py3.3+ supports the u"..." string prefix, and, if
|
|
present, the prefix may provide useful information for disambiguating
|
|
between byte strings and unicode strings, which is often the hardest part
|
|
of the porting task.
