Reading such stories always reminds me of taking the TOEFL test. At least at the time, their website was full of all sorts of warnings and threats about what would happen if you registered with a name that did not match the legal name on your ID. Yet their website did not let me enter the letter "รค" in the name field.
What makes this all the more puzzling is that TOEFL is presumably aimed at people who are not native English speakers, so you would expect all sorts of non-ASCII characters to be fairly common.
