With the caveat that I know absolutely nothing about locales, here's what I've been able to reduce the problem down to:
zinc (alias s11, Solaris 11 x64):
 >>> locale.setlocale(locale.LC_ALL, 'C')
 'C'
 >>> locale.strxfrm('a')
 'a'
 >>> locale.setlocale(locale.LC_ALL, 'en_US.UTF-8')
 'en_US.UTF-8'
 >>> locale.strxfrm('a')
 Traceback (most recent call last):
 File "<stdin>", line 1, in <module>
 ValueError: character U+10105a3 is not in range [U+0000; U+10ffff]
 >>> 
nitrogen (alias s10, Solaris 10 SPARC):
 >>> locale.setlocale(locale.LC_ALL, 'en_US.UTF-8')
 'en_US.UTF-8'
 >>> locale.strxfrm('a')
 Traceback (most recent call last):
 File "<stdin>", line 1, in <module>
 ValueError: character U+101010e is not in range [U+0000; U+10ffff]
Not sure how relevant it is, but on both those Solaris boxes, locale.LC_ALL returns 6, whereas on BSD and OS X it always seems to return 0.
