Question

I want to transform UTF-8 strings using built-in functions such as upper() and capitalize().

For example:

>>> mystring = "işğüı"
>>> print mystring.upper()
Işğüı  # should be İŞĞÜI instead.

How can I fix this?

Answer 1

Do not perform actions on encoded strings; decode to unicode first.

>>> mystring = "işğüı"
>>> print mystring.decode('utf-8').upper()
IŞĞÜI
