Notes on conversion from type M to type N

The fullwidth characters in the input data are converted to the codes of the encoding of the output data. Also, as in the example, if the output area is larger than the actual output data size, the data is padded with fullwidth spaces.

In the conversion from type M to type N, if the input data contains a halfwidth character, a conversion error is generated. In this example, an error occurs when the character ｱ is detected.
