Comment (by pento):

 == TEST 3

 Convert the regex to match against UTF-32 byte patterns. My theory is that
 fixed byte length characters will be faster to match, as they're also
 faster to process in the `mb_*()` functions.

 Data: https://travis-ci.org/pento/test-41501/builds/260073851

 Analysis:
 - It's slower across all PHP versions, string lengths, languages, and
 emoji usage.

 Conclusion: Test 3 should not be included.
