Oh crumbs. That's true. We could also just use strict or ever not support
unicode in Python 2 *at all*; the number of unicode paths in Py2 in
mercurial should be 0 *anyway*. The function is mostly there to make it
easier to write code that works both on 2 and 3 and the encoding is only
needed in 3 really.
