My computer has an ASCII name, so I even not realized, what happens. Did all these things on another win7 and everything was ok. Maybe someone can help with?

UPD. My problem was due to the changed 'hosts' file - there are a lot of disabled addresses. Thanks all for the answers.

Answer 1

使用python3，如果您使用python2.x，许多字母（例如重音符号或其他字母）会导致异常崩溃

Answer 2

try this:

a.encode('utf-8').strip()

if "a" is the string with non-ascii character
