I even had trouble booking flight tickets since their security system couldn't parse my name, and then had to go through some special security check due to it returning errors. After that, never again. Not sure how they managed to do it but they had some basic rules that they used to say "no real name can look like this, this is a fake person!" and just kicked it out.
'standard' by what measure? Ł is more standard than X or Q in the polish alphabet.
~ Sincerely, a person whose name contains „ń” and therefore had to deal with this bullshit his entire life.
Edit: You know how aircraft travel security always transforms your name into letters from the English alphabet to parse? Yeah, it transformed my name and then the resulting string looked so bad that the system rejected that. The original name doesn't look bad, but after transformations it did...
Standard characters (ie english) are only used by a small subset (maybe 5-10%) of the global population.
Changing all software to respect their perfectly valid name isn't something they can do.
They shouldn't need to change their name, but if they do, they can ignore all the broken software and go about their day.
This particular user is more capable than most, and found a workaround for this particular problem, which is good... But this is not likely to be the last of the problems.
