'briefcase run web' fails when app name contains non-ascii character

[jkomalley]

Describe the bug

When you run 'briefcase run web' on a project that's app name contains a non ascii character the static site fails to launch. I believe this is because the app's wheels are generated with the non ascii characters in the file name.

Steps to reproduce

1. create a briefcase project with an app name containing a non ascii character: briefcase new (followed by entering something like helloworldı for the app name)
2. run that project: briefcase run web
3. see error when browser opens Note: this will also likely fail for all platforms until Ref #1011 is resolved

Expected behavior

Wheel's should be generated with only non ascii characters and static web app should run normally.
