Remove special code for CJK that is no longer required after
we use CJKutf8 document-wide with inputenc "utf8-cjk"
(and "utf8" for languages requiring CJK) (since 7bbf333fa1).
CJK characters can no longer be used with a document-wide 8-bit encoding.
(Hint: Use utf8-cjk or one of the CJK legacy encodings if your document contains CJK characters.)
