Preparing 1.5.1 steps 4/16 4. python setup.py check failed doc/announcement.txt contains non-ascii: 'ascii' codec can't encode character u'\xe9' in position 6698: ordinal not in range(128) It was hard to find u'\xe9', because setup.py encoded text to 'utf8' before final check. After removing encoding step: doc/announcement.txt contains non-ascii: 'ascii' codec can't decode byte 0xc3 in position 6698: ordinal not in range(128) Which is fixed. Also fixed reST warning caused by |u symbol: warning: check: Inline substitution_reference start-string without end-string. (line 156)
