Nit: ┐ isn't emoji. It's a box drawing character, and they've been around in one form or another since at least the 80s. The modern form has been part of Unicode from (nearly?) the beginning. In any case, the character itself is unrelated to the bug. As someone pointed out in the bug thread, certain Cyrillic strings will also cause it.
