My favorite experience was with the backspace character. One of our cli tools accidentally saved them in a password store. The user can show his password but the console interpreted the backspace and therefore everything looked normal. That discovery was truly funny. Null byte characters create a funny user experience too. A user has an issue with an input, then I go and fix the problem by typing the same thing again and it works. These can end up in passwords too.
