 * Encoding flags that apply to multiple data types.
 */
/*
 * The encoding of a field of a particular type may involve more
 * than just whether it's big-endian or little-endian and its size.
 *
 * For integral values, that's it, as 99.9999999999999% of the machines
 * out there are 2's complement binary machines with 8-bit bytes,
 * so the protocols out there expect that and, for example, any Unisys
 * 2200 series machines out there just have to translate between 2's
 * complement and 1's complement (and nobody's put any IBM 709x's on
 * any networks lately :-)).
 *
 * However:
 *
 *  for floating-point numbers, in addition to IEEE decimal
 *  floating-point, there's also IBM System/3x0 and PDP-11/VAX
 *  floating-point - most protocols use IEEE binary, but DCE RPC
 *  can use other formats if that's what the sending host uses;
 *
 *  for character strings, there are various character encodings
 *  (various ISO 646 sets, ISO 8859/x, various other national
 *  standards, various DOS and Windows encodings, various Mac
 *  encodings, UTF-8, UTF-16, other extensions to ASCII, EBCDIC,
 *  etc.);
 *
 *  for absolute times, there's UNIX time_t, UNIX time_t followed
 *  by 32-bit microseconds, UNIX time_t followed by 32-bit
 *  nanoseconds, DOS date/time, Windows FILETIME, NTP time, etc..
 *
 * We might also, in the future, want to allow a field specifier to
 * indicate the encoding of the field, or at least its default
 * encoding, as most fields in most protocols always use the
 * same encoding (although that's not true of all fields, so we
 * still need to be able to specify that at run time).
 *
 * So, for now, we define ENC_BIG_ENDIAN and ENC_LITTLE_ENDIAN as
 * bit flags, to be combined, in the future, with other information
 * to specify the encoding in the last argument to
 * proto_tree_add_item(), and possibly to specify in a field
 * definition (e.g., ORed in with the type value).
 *
 * Currently, proto_tree_add_item() treats its last argument as a
 * Boolean - if it's zero, the field is big-endian, and if it's non-zero,
 * the field is little-endian - and other code in epan/proto.c does
 * the same.  We therefore define ENC_BIG_ENDIAN as 0x00000000 and
 * ENC_LITTLE_ENDIAN as 0x80000000 - we're using the high-order bit
 * so that we could put a field type and/or a value such as a character
 * encoding in the lower bits.

 * Encoding for character strings - and for character-encoded values

 *
 * Historically, the only place the representation mattered for strings
 * was with FT_UINT_STRINGs, where we had false for the string length
 * being big-endian and true for it being little-endian.
 *
 * We now have encoding values for the character encoding.  The encoding
 * values are encoded in all but the top bit (which is the byte-order
 * bit, required for FT_UINT_STRING and for UCS-2 and UTF-16 strings)
 * and the bottom bit (which we ignore for now so that programs that
 * pass true for the encoding just do ASCII).
 *
 * For ENC_ASCII, we map ASCII characters with the high bit set to the UTF-8
 * REPLACEMENT CHARACTER, and do the same for ENC_UTF_8 with invalid UTF-8
 * sequences. We should also map 0x00 to that as well - null-terminated and
 * null-padded strings never have NULs in them, but counted strings might.
 * Either that, or strings should be counted, not null-terminated. Note
 * that conversion of ASCII and UTF-8 can change the length of the string,
 * as with any other encoding, due to REPLACEMENT CHARACTERs.
 *
 * For display, perhaps we should also map control characters to the
 * Unicode glyphs showing the name of the control character in small
 * caps, diagonally.  (Unfortunately, those only exist for C0, not C1.)
 *
 * *DO NOT* add anything to this set that is not a character encoding!

 *  timespec with a 4-byte or 8-byte time_t or a structure with an
 *  8-byte time_t and an 8-byte nanoseconds field.)
 *
 *  ENC_TIME_NTP - 8 bytes; the first 4 bytes are seconds since the NTP
 *  epoch (1900-01-01 00:00:00 GMT) and the next 4 bytes are 1/2^32's of

 *  second since the NTP epoch, with the upper 32 bits first and the
 *  lower 32 bits second, even when little-endian.)  A value of 0 is a
 *  special case representing unknown or unsynchronized time.  Per the
 *  suggestion in RFC 4330, if bit 0 is not set then the time is assumed
 *  to be in NTP Era 1, beginning on 2036-02-07 06:28:16 UTC.  (I.e., the
 *  time displayed will be between 1968-01-20 03:14:08 UTC and
 *  2104-02-26 09:42:24 UTC.)  The 16 byte NTP date format and the 4 byte
 *  NTP short relative time format are not supported.
 *  Encodings that store only the seconds since the NTP epoch without
 *  fractional seconds should use ENC_TIME_SECS_NTP, described below.
 *
 *  ENC_TIME_TOD - 8 bytes, as a count of microseconds since the System/3x0
 *  and z/Architecture epoch (1900-01-01 00:00:00 GMT).
 *
 *  ENC_TIME_RTPS - 8 bytes; the first 4 bytes are seconds since the UN*X
 *  epoch and the next 4 bytes are 1/2^32's of a second since that
 *  second.  (I.e., it's the offspring of a mating between UN*X time and
 *  NTP time).  It's used by the Object Management Group's Real-Time
 *  Publish-Subscribe Wire Protocol for the Data Distribution Service.
 *
 *  ENC_TIME_SECS_USECS - 8 bytes; the first 4 bytes are seconds and the
 *  next 4 bytes are microseconds.  If the time is absolute, the seconds
 *  are seconds since the UN*X epoch.  (I.e., a UN*X struct timeval with
 *  a 4-byte time_t.)
 *
 *  ENC_TIME_SECS - 4 to 8 bytes, representing a value in seconds.
 *  If the time is absolute, it's seconds since the UN*X epoch.
 *
 *  ENC_TIME_MSECS - 6 to 8 bytes, representing a value in milliseconds.
 *  If the time is absolute, it's milliseconds since the UN*X epoch.
 *
 *  ENC_TIME_USECS - 8 bytes, representing a value in microseconds.
 *  If the time is absolute, it's microseconds since the UN*X epoch.
 *
 *  ENC_TIME_NSECS - 8 bytes, representing a value in nanoseconds.
 *  If the time is absolute, it's nanoseconds since the UN*X epoch.
 *
 *  ENC_TIME_SECS_NTP - 4 bytes, representing a count of seconds since
 *  the NTP epoch.  As with ENC_TIME_NTP, times are assumed to be in
 *  the upper half of NTP Era 0 or the lower half of NTP Era 1.
 *
 *  ENC_TIME_RFC_3971 - 8 bytes, representing a count of 1/64ths of a
 *  second since the UN*X epoch; see section 5.3.1 "Timestamp Option"
 *  in RFC 3971.
 *
 *  ENC_TIME_MSEC_NTP - 6-8 bytes, representing a count of milliseconds since
 *  the NTP epoch.  Similar to ENC_TIME_NTP, times before the midpoint of
 *  NTP Era 0 (1968-01-20) are assumed to represent the corresponding
 *  time in NTP Era 1 instead.
 *
 *  ENC_TIME_MIP6 - 8 bytes; the first 48 bits are seconds since the UN*X epoch
 *  and the remaining 16 bits indicate the number of 1/65536's of a second
 *  since that second.
 *
 *  ENC_TIME_MP4_FILE_SECS - 4-8 bytes, representing a count of seconds since
 *  January 1, 1904, 00:00:00 UTC.
 *
 *  ENC_TIME_ZBEE_ZCL - 4-8 bytes, representing a count of seconds  since
 *  January 1, 2000, 00:00:00  UTC.
