bug#27965: 25.2; \cj does not match some Japanese characters

[ynyaaa]

(string-match "\\cj"
              (mapconcat (lambda (l) (string (apply #'make-char
                                                    'japanese-jisx0213.2004-1
                                                    l)))
                         '((46 33) (47 126) (79 84) (79 126)
                           (116 39) (126 122) (126 123) (126 124))
                         ""))
=> nil

These characters belong to 'japanese-jisx0213.2004-1,
but does not belong to 'japanese-jisx0213-1.
