These procedures interpret their bytevector argument as a UTF-8 or UTF-16 encoding of a sequence of characters, and return a text containing that sequence.

The bytevector subrange given to utf16->text may begin with a byte order mark (BOM); if so, that BOM determines whether the rest of the subrange is to be interpreted as big-endian or little-endian; in either case, the BOM will not become a character in the returned text. If the subrange does not begin with a BOM, it is decoded using the same implementation-dependent endianness used by textual->utf16.

The utf16be->text and utf16le->text procedures interpret their inputs as big-endian or little-endian, respectively. If a BOM is present, it is treated as a normal character and will become part of the result.

It is an error if the bytevector subrange given to utf8->text contains invalid UTF-8 byte sequences. For the other three procedures, it is an error if start or end are odd, or if the bytevector subrange contains invalid UTF-16 byte sequences.
