Welcome back to, Ruby programmers write bad regular expressions.
Edit: This was slander, the Regex is fine. It's so much worse.
Apple has a feature called LiveText that lets you copy text out of an image. If you had asked me yesterday, I would have said it was magic. I'm never using it again.
Cyrillic Capital Letter Em (U+041C)
That's why the Regex didn't match.
