Issue

I've read #798 and #4258, those issues deal with "post-init", my issue is with/about init.

As stated in the title, poetry init does not allow for é to exist in the authors field.

Author [José Duarte <redacted>, n to skip]:  
Invalid author string. Must be in the format: John Smith <john@example.com>

If I try Jose... instead, it works though.

I didn't try other characters, but I'd suspect they also fail.
