I'm somewhat wondering to what extent a bank is required to support storing the names natively. I mean something like "${name} spelled with an acute accent on the e" would be technically a correct description even if it is impractical to use. The GDPR does grant you the right to correct your personal information but doesn't specify how this information is represented. As far as I can tell the GDPR also doesn't grant the customer the right to have their name represented correctly on their bank pass (otherwise everyone with a long surname would require impractically long bank passes), the court only ruled that the inability of the bank to store the name correctly simply isn't an excuse.
