There has been a relatively recent discussion of case mappings under #12753 (msg144836). I personally agree with Martin: str.upper/lower should remain the way it is - a simplistic 1-to-1 mapping using UnicodeData.txt fields. More sophisticated case mapping algorithms belong to a specialized library module not python core. The behavior of .title() and .capitalize() is harder to defend, so if someone can point out to a python library (PyICU?) that gets it right we can reference it in the documentation.
