66 use month and weekday enums (above) which are zero-based.

68 The encoded strings are multibyte strings in the C locale which
69 reflect the same binary data as the expected strings. When you run
70 the test, the strings are printed as-is to stdout, so if your
71 terminal is set for the correct encoding, they'll be printed
72 "correctly". Put the Unicode codes and UTF-8 samples in the
73 comments.
74
75 For convenience, mis-matched strings are printed in
76 paste-compatible format, raw text format, and Unicode format. Use
77 "" between a hex escape sequence (like \xe8) and a following hex
78 digit which should be considered as a printable character.
79
80 To verify text, save the correct text in a file, and use "od -tx1
81 -tc file" to see the raw hex values. */
