As someone with so called “Unicode-characters” in my name, I have encountered bugs and issues on every single American website in the history of the internets, and you will have to forgive me for preferring correctness over programmer convenience.
While your comment is trollish, I’ll let you know I’ve had many issues with payments because shitty web-sites have been unable to 1. Validate my name and 2. Correlate whatever their whitelist permits with actual information returned from the payment processor.
So your inability to handle basic stuff like this is actually costing you money.
For me it’s literally personal.
