Flickr expects every text to be encoded in UTF-8. The Python Flickr API can help you in a limited way. If you pass a unicode string, it will automatically be encoded to UTF-8 before it’s sent to Flickr. This is the preferred way of working, and is also forward-compatible with the upcoming Python 3.
If you do not use unicode strings, you’re on your own, and you’re expected to perform the UTF-8 encoding yourself.
Here is an example:
flickr.photos.setMeta(photo_id='12345',
title=u'Money',
description=u'Around \u20ac30,-')
This sets the photo’s title to “Money” and the description to “Around €30,-”.
