encoding: improve handling of buggy getpreferredencoding() on Mac OS X Prior to version 2.7, calling locale.getpreferredencoding() would always return 'mac-roman' on Mac OS X. Previously, this was handled by a call to locale.setlocale(). Unfortunately, Python 2.6.5 and older have a bug where isspace() would incorrectly report True for 0x85 and 0xa0 after such a call. In order to fix this, we replace the previous _encodingfixup mapping to an _encodingfixers mapping. Rather than mapping encodings to their replacement, it maps them to a function returning the replacement. This allows us to provide an simplified implementation of getpreferredencoding() which extracts the expected encoding and restores the locale. This fix is based on a patch originally submitted by Martijn Pieters as well as feedback from Brodie Rao.

templatefilters: use \uxxxx style escape for JSON string It's embeddable in plain javascript, and also conforms to JSON standard.

test-notify: make it pass on Mac OS X (again) Changeset 25e74cd3f023 (from 2008) introduced a hack to handle the very long values of $TMPDIR typically seen on Mac OS X. This hack expected continuation lines to begin with a tab. However, as a result of a change in Python 2.7, changeset 594b98846ce1 made it so continuation lines began with a tab. Since then, `test-notify' has been broken on Mac OS X. Merely replacing the tab in the regular expression with a space will not work: not only do tab continuations still occur in the message, but other lines -- in the body of the message -- also start with a space. Luckily, all broken up lines appear to end with either a colon or an n, so we can match those, and reinsert them in the replacement.
