Dist::Zilla::Plugin::Test::MixedScripts - author tests to ensure there is no mixed Unicode

In the dist.ini add:

[Test::MixedScripts]
; authordep Test::MixedScripts
script = Latin
script = Common

This generates an author Test::MixedScripts.

This is an extension of Dist::Zilla::Plugin::InlineFiles, providing the file xt/author/mixed-unicode-scripts.t for testing against mixed Unicode scripts that are potentially confusing or malicious.

For example, the text for the domain names оnе.example.com and one.example.com look indistinguishable in many fonts, but the first one has Cyrillic letters. If your software interacted with a service on the second domain, then someone can operate a service on the first domain and attempt to fool developers into using their domain instead.

This might be through a malicious patch submission, or even text from an email or web page that they have convinced a developer to copy and paste into their code.
