Within Payeezy Gateway, double-byte character sets (e.g. Japanese Kanji and Hiragana) can be used by certain Payment Page settings, like the title, but cannot be used for anything to do with processing (e.g. cardholder name, reference fields, etc…). Payeezy Gateway’s authorization/settlement platform, Compass, uses the ASCII character set, which does not support a double-byte character set(s). Within Payeezy Gateway, the support for double-byte character sets is very limited and wouldn't be recommended for use for anything other than display-only fields. This rules out almost all use in RPM (e.g. POS, Quick key, etc..), API, and Recurring, and has limited support in Payment Pages.
