Backport two fixes to testSplitterLocaleAwareness() from the Zope 3

version:

- If the setlocale() call fails, don't fail the test -- just skip it
  silently.  XXX This is not ideal, but what else can we do?  Locale
  names are not standardized; the test fails on Mac OSX, and
  apparently on older Linux versions (e.g. my Mandrake 8.1).

- Don't use non-ASCII literals; use \xXX escapes.
