Discriminating against a non small part of the population of the country you work in is stupid???

You know what is stupid, the attitude of "works for me must work for everyone". It's objectively stupid because it has caused probably not just millions but billions of damages.

The huge majority of widely spoken languages in the world does use letters not contained in us-ascii, this applies to names, too.

I mean, this about business requirements not tech. The bank can use any encoding they want to accomplish their requirements. Nobody is dictating a specific technical standard just the results.

Sadly, Hacker News hasn't been for or about hacker culture for a decade. It's become a "normie" programming-oriented news site.

This is not hackers culture - it's about bank controlling 'technology' and option to do as they please - because they employ "hackers"

I can't say if this law is stupid or not.

A company has to be over 250 employés to be GDPR compliant. And it seems there is UTF-EBCDIC.

I can see what you mean, but I don't think having rules for large banks is against the ~hacker etos~
