A Latin-1 text string containing the name of the transport form, e.g. "UTF-8" or "UTF-16LE".

Use size_of_uchar c to compute the number of octets required to represent c in this transport form.

Use s#scan uchar_decode_scheme to scan the next Unicode code point available as encoded octets to s. Raises Cf_decode.Invalid if the octets do not comprise a valid Unicode character.

Use e#emit of_char uchar_encode_scheme c to emit c as encoded octets with e.

Use s#scan bom_decode_scheme to scan the octets of the next code point in the stream and, if they are the encoding of the Unicode Byte Order Mark (BOM) character, U+FEFF, to produce the unit value. Raises Cf_decode.Invalid if the octets do not comprise a BOM character.

Use e#emit bom_encode_scheme `UTF8 to emit the encoding of the Unicode Byte Order Mark (BOM) character, U+FEFF.

Use seq_of_scanner sxr to make a volatile sequence that scans Unicode characters with sxr. Consuming the sequence can raise exceptions from

f_decode

.

Use seq_of_string str to make a volatile sequence that scans Unicode characters from str. Consuming the sequence can raise exceptions from

f_decode

.

Use seq_of_slice str to make a volatile sequence that scans Unicode characters from str. Consuming the sequence can raise exceptions from

f_decode

.

Use seq_to_emitter exr s to consume all the Unicode characters in s and emit them with exr.

Use seq_to_string s to make a string containing all the Unicode characters in s encoded according to the transport form. Raises Failure if more than Sys.max_string_length octets are required.

Use validate_string s to raise Cf_decode.Invalid with the position in s of the first invalid octet. Returns normally if the string is a valid encoding.

Use validate_slice s to raise Cf_decode.Invalid with the position in s of the first invalid octet. Returns normally if the slice comprises a valid encoding.

Use is_valid_string s to test whether s comprises a valid encoding of octets in the transport form.

Use is_valid_slice s to test whether s comprises a valid encoding of octets in the transport form.
