>What if your game needs to talk to a server and do some string manipulation in between requests? Are you really going to architect everything so that the client doesn't need to handle any of that ever? Of course! Your string manipulation with user entered attributes like display names or chat messages are 1 millimeter away from old good sql 'Bobby; drop table students'. Never ever do that if you can avoid it. Every time someone 'just concatenates' two strings like to add ie 'symbol that represents input button' programmer makes bad bug that will be both annoying and wrong. Games should use substitution patterns guided by translation team. Because there is no ASCII culture in like around 15 typically supported by big publishers. There are exceptions like platform provided services to filter ban words in chat. And even there you don't have to do 'things with ASCII characters'. Yeah, players will input unsupported symbols everywhere they can and you need to have good replacement characters for those and fix support for popular emojis regularly. That is expected by communities now.
