.baseFiles() returns a unicode instead of string

[jservonnat]

@rigoudyg the .baseFiles() method of the climaf dataset returns now a unicode instead of a string. Is it on purpose? If yes I will fix the bugs associated with this change wherever I find them, if not can we simply keep the string as output?

@rigoudy actually it looks like all other methods return unicodes instead of string... this is the case for .crs, cfile() (not if target is specified),

@jservonnat yes, this change is expected. Unicode becomes the default for strings in python3.

To bypass this difficulty, you should at least do the following changes :

• add the following lines at the top of all your python scripts (it will turn the default strings to unicode): #!/usr/bin/env python # -*- coding: utf-8 -*- from __future__ import print_function, division, unicode_literals, absolute_import
• add the following import: import six
• when checking that a element is a string, turn to that check: if isinstance(elt, six.string_types)

It should resolve most problems with encoding.
