I’ve come across this password problem and various DB and webform issues. What are perfectly sensible controls for everyone with more than one letter in their surname get screwed up by us lovely exceptions. It’s not their fault we are awkward. Once they know about it, they *could* change the system, but if it really is just 2 people in the country/world it’d probably be cheaper for them to pay us to change our names! I spell it ‘Qu’ if I find database issues, I’m consistent and when I have actual people in front of me I explain. Here, the onus is on you to come up with a password that doesn’t have a Q in it.
