	10 # This is not a real CNS-11643 table, but a "fake" table to return U+FFFD

	11 # for every byte sequence valid in ISO-2022-CN(-Ext). Chrome and Android

	12 # do not want to include the real table for charsets that are extremely

	13 # rare, if used at all. However, not supporting ISO-2022-CN(-Ext) gets

	14 # them vulernable to a security issue. By including this 'fake' table,

	15 # they can be protected while increasing the ICU data size by ~ 10kB.
