Convert Unicode/UTF-8 string to lower/upper case using pure & pythonic library

Question

I use Google App Engine and cannot use any C/C++ extension, just pure & pythonic library to do conversion of Unicode/UTF-8 strings to lower/upper case. str.lower() and string.lowercase() don't.

Accepted Answer

`str` encoded in UTF-8 and `unicode` are two different types. Don't use `string`, use the appropriate method on the unicode object:

```
>>> print u'ĉ'.upper()
Ĉ
```

Decode `str` to `unicode` before using:

```
>>> print 'ĉ'.decode('utf-8').upper()
Ĉ
```
