Comment 8 for bug 1694261

I reproduced the bug in a fresh xenial container: I simply installed moin and apache in a new container, added moin as a wsgi script in apache and tried to create an /à page in the wiki. I guess the same also happens on trusty, but I don't have time to install moin in another container.

For the possible regression, as Mattia said in the chat log I don't think it will cause any regression: ASCII can be considered a subset of UTF-8, so even if someone forces ASCII for whatever reason nothing should break.
