A problem when converting jis-string to utf-8

[horasal]

In this call
mahonia.NewDecoder("shift-jis").ConvertString(string(s))

if string(s) contain char "", it will be converted to "¥"（ full-width）, which may lead to an error when creating file.

The following code can avoid this problem without changing original package
strings.Replace(mahonia.NewDecoder("shift-jis").ConvertString(string(s)), "¥", "", -1)
