Just something I stumped across. Apparently the invalid string "هقتاغققع" in Arabic is translated as "http://www.youtube.com/watch?" in English and almost all other locales (didn't test them all), in Lingala it even adds invalid text to it: https://translate.google.com/?sl=auto&tl=ln&text=%D9%87%D9%8...

Screenshot in case it doesn't work tomorrow or it's fixed later: https://ibb.co/4JxhN9p
