In Python 2 it's not possible to add the representation of list containing a pages containing non-ASCII characters into a Unicode string:
```
>>> import pywikibot
>>> p = pywikibot.Page(pywikibot.Site(), u'öäöä')
>>> p.title()
u'\xf6\xe4\xf6\xe4'
>>> '%r' % ([p],)
'[Page(\xc3\xb6\xc3\xa4\xc3\xb6\xc3\xa4)]'
>>> u'%r' % ([p],)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 6: ordinal not in range(128)
```
This is with 41d4254c which was the commit before merging unicode_literals. With unicode_literals it seems that repr doesn't correctly work at all:
```
>>> u'%r' % ([p],)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
UnicodeEncodeError: 'ascii' codec can't encode characters in position 5-12: ordinal not in range(128)
>>> '%r' % ([p],)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
UnicodeEncodeError: 'ascii' codec can't encode characters in position 5-12: ordinal not in range(128)
>>> repr(p)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
UnicodeEncodeError: 'ascii' codec can't encode characters in position 5-12: ordinal not in range(128)
```
