UCS-4 or other encoding with a 32-bit code unit and ASCII 　　characters encoded as ASCII values, in respectively big-endian (1234), little-endian 　　(4321) and two unusual byte orders (2143 and 3412). The encoding declaration 　　must be read to determine which of UCS-4 or other supported 32-bit encodings 　　applies. 　　UTF-16BE or big-endian ISO-10646-UCS-2 　　or other encoding with a 16-bit code unit in big-endian order and ASCII characters 　　encoded as ASCII values (the encoding declaration must be read to determine 　　which) 　　UTF-16LE or little-endian 　　ISO-10646-UCS-2 or other encoding with a 16-bit code unit in little-endian 　　order and ASCII characters encoded as ASCII values (the encoding declaration 　　must be read to determine which) 　　UTF-8, ISO 646, ASCII, some part of ISO 8859, Shift-JIS, EUC, or any other 　　7-bit, 8-bit, or mixed-width encoding which ensures that the characters of 　　ASCII have their normal positions, width, and values; the actual encoding 　　declaration must be read to detect which of these applies, but since all of 　　these encodings use the same bit patterns for the relevant ASCII characters, 　　the encoding declaration itself may be read reliably 　　EBCDIC (in some flavor; the full encoding declaration 　　must be read to tell which code page is in use) 　　Other 　　UTF-8 without an encoding declaration, or else the data stream is mislabeled 　　(lacking a required encoding declaration), corrupt, fragmentary, or enclosed 　　in a wrapper of some kind
