Credit Card validation: can Card Name contain non-ASCII characters?

Question

Can the Card Name (i.e. the cardholder name, not the card type) contain non-ASCII characters? Example: \"JOSÉ GONZÁLEZ\".

Answer 1

Chip cards (aka smart Cards, EMV cards) contain and can return a plethora of different values including "Cardholder Name" (tag 5F20) and "Cardholder Name Extended" (tag 9F0B). EMV Co. says that both of these tags should follow ISO 7813 but I've already seen one card (an "NH Card" from Korea Air) in which tag 5F20 contained lowercase characters.
