Tests break against python3-pygments (=2.10.0+dfsg-1)

[AlexGhiti]

Hi,

We (Debian/Ubuntu) are updating python3-pygments to 2.10, but then it breaks pygments.rb package as reported here [1]. I tried to update the pygments.rb package to 2.2.0, and then the only remaining failures are related to UTF-8 expected encoding whereas ASCII is provided.

Could you give us a hand to fix those failures?

Thanks!

I believe it was this change: https://github.com/pygments/pygments/pull/1780/files#diff-8b5c2178a004022575a5a9e7dc5184d9bf3355ab9d7f45be7b14a9e6a6f9f8d1L36

I'll adjust our tests.

For the history: the problem is not UTF-8 vs ASCII. The problem is rb vs ruby.
