UnicodeDecodeError: 'ascii' codec can't decode byte 0x9f in position 36: ordinal not in range(128)

[Lukasz]

How to Reproduce

While doing a GET operation on /browser/tags/--PRIVATE-DATA-REMOVED---, Trac issued an internal error.

(please provide additional details here)

My observation: the file processed has a Date SVN keyword which, after substitution, expands to non-ascii string (Polish "Paź." for month name).

Request parameters:

{u'format': u'zip', 'path': u'/tags/--PRIVATE-DATA-REMOVED---', u'rev': u'1154'}
