-JC:<number>:<new_code>=old_code[y|t]:...:new_code=old_code[y|t]
In <number>, the total number (of definitions) of a converted character is given by a decimal number. <new_code> and <old_code> are four-digit hexadecimal numbers. JIS codes are converted from the <old_code> characters to the <new_code> characters.
By default, both the vertical characters and horizontal characters are converted.
If "y" is specified, only the horizontal characters are converted. If "t" is specified, only the vertical characters are converted.
The search starts from the beginning, only the first conversion found is valid.
