[ovirt-devel] unicode_literrals vs "u''" vs six.text_type

Hi all, That's a "sub-thread" of "unicode sandwich in otopi/engine-setup". I was recommended to use 'six.text_type() over "u''". I did read [1], and eventually decided that my own preference is to just add "u" prefix. Reasoning is inside [1]. Do people have different preferences/reasoning they want to share? Do people think we should have project-wide policy re this? Personally, I do not see the big advantage of adding "six.text_type()" (15 chars) instead of a single "u". I do see where it can be useful, but not as a very long replacement, IMO, for "u", or for unicode_literrals. Thanks and best regards, [1] http://python-future.org/unicode_literals.html -- Didi
