/* Notes:

   Years are full 4-digit years, the code compensates.  Likewise,
   use month and weekday enums (above) which are zero-based.

   The encoded strings are multibyte strings in the C locale which
   reflect the same binary data as the expected strings.  When you run
   the test, the strings are printed as-is to stdout, so if your
   terminal is set for the correct encoding, they'll be printed
   "correctly".  Put the Unicode codes and UTF-8 samples in the
   comments.

   For convenience, mis-matched strings are printed in
   paste-compatible format, raw text format, and Unicode format.  Use
   "" between a hex escape sequence (like \xe8) and a following hex
   digit which should be considered as a printable character.

   To verify text, save the correct text in a file, and use "od -tx1
   -tc file" to see the raw hex values.  */
