+//    Recognizers for specific mbcs encodings make their "characters" available
+//    by providing a nextChar() function that fills in an instance of IteratedChar
+//    with the next char from the input.
+//    The returned characters are not converted to Unicode, but remain as the raw
+//    bytes (concatenated into an int) from the codepage data.
+//
+//  For Asian charsets, use the raw input rather than the input that has been
+//   stripped of markup.  Detection only considers multi-byte chars, effectively
+//   stripping markup anyway, and double byte chars do occur in markup too.
