I got a variant of 39 just today, but it's very frequent in Japan: the field for the name required at most 16 full-width characters. Standard Latin characters are rejected because they're half-width. If you really want Latin characters, you have to go with characters in the range U+FF21 to U+FF5A, although in many cases, they are rejected, and you have to go with katakana. Which is also asked for separately.
