  Name:         ConvertUnicodeCallback

  Description:  The callback configured in the STD_ConvertStringSjisToUnicode function.

  Arguments:    dst: The pointer that stores the converted Unicode characters
                dstlen: Number of characters in dst actually converted
                src: The pointer that indicates the Shift-JIS characters that should be converted
                srclen: Byte size of src that should continue being read by conversion

  Returns:      The number of characters converted.
