Reproducing ruby/ruby#21709

Ruby's Regexp interpolation rejects fragments of differing encodings, while String interpolation silently upgrades them to UTF-8. With prefix = '\p{In_Arabic}' and suffix = prefix.encode('US-ASCII'), /#{prefix}#{suffix}/ raises a RegexpError while "#{prefix}#{suffix}" builds a UTF-8 string fine. The two interpolation forms should agree on how to combine fragments of different encodings — they don't.
