// From FTS-0001.16:
// "Message text is unbounded and null terminated (note exception below).
//
// A 'hard' carriage return, 0DH, marks the end of a paragraph, and must
// be preserved.
//
// So called 'soft' carriage returns, 8DH, may mark a previous
// processor's automatic line wrap, and should be ignored. Beware that
// they may be followed by linefeeds, or may not.
//
// All linefeeds, 0AH, should be ignored. Systems which display message
// text should wrap long lines to suit their application."
//
// This is a bit tricky. Decoding the buffer to CP437 converts all 0x8d -> 0xec, so we'll
// have to replace those characters if the buffer is left as CP437.
// After decoding, we'll need to peek at the buffer for the various kludge lines
// for charsets & possibly re-decode. Uggh!
//
// :TODO: Use the proper encoding here. There appear to be multiple specs and/or
// stuff people do with this... some specs kludge lines, which is kinda durpy since
// to get to that point, one must read the file (and decode) to find said kludge...
