Code review comment for lp:~gagern/bzr/setlocale

Digging through old list archives, it seems this branch has been mostly obsoleted by now, as a number of individual features have been spliced out and merged. I'm quoting merging bzr.dev revision numbers and mailing list subjects:

3518: setlocale mini (#128496)
3528: Remove unused call to format_date
3529: Improved UnicodeFilenameFeature
3754: local weekday support

The only remaining issue seems to be from a mailing list thread with subject "More robust handling of encoding issues in tests". I've just updated it to match current bzr.dev and pushed it to lp:~gagern/bzr/encodingSafeTests
