+# This is not a real CNS-11643 table, but a "fake" table to return U+FFFD
+# for every byte sequence valid in ISO-2022-CN(-Ext). Chrome and Android
+# do not want to include the real table for charsets that are extremely
+# rare, if used at all. However, not supporting ISO-2022-CN(-Ext) gets
+# them vulernable to a security issue. By including this 'fake' table,
+# they can be protected while increasing the ICU data size by ~ 10kB.
