Even in english, you still have emoiji that use ZWJ characters. e.g. 🏳️🌈 has "invisible" characters. There are all sorts of control characters in unicode that usually do nothing but sometimes do something.

But one has to be very careful about these things. - Bawolff On Tuesday, January 17, 2023, Amir Sarabadani <[email protected]> wrote: > Disallowing invisible characters or cleaning them is a bad idea. > > Invisible characters are actually heavily used in many languages including > Persian (and part of the official manual of style of the language taught in > schools) it is downright wrong to check and fix those in many wikis in > those languages. > > Also many wikis have titles in other languages such as wiktionaries or > redirects in a different languages (For example: > https://en.wikipedia.org/w/index.php?title=%D8%AA%D9%87% > D8%B1%D8%A7%D9%86&redirect=no) which means removing ZWNJ or similar > characters would be also unacceptable in English Wiktionary or English > Wikipedia as well. > > There are some exemptions though: Two invisible characters are wrong, or > an invisible character at the end or beginning.
