6.6.12.6 Interpreting Bytevector Contents as Unicode Strings ¶

Bytevector contents can also be interpreted as Unicode strings encoded in one of the most commonly available encoding formats. See Representing Strings as Bytes, for a more generic interface.

(utf8->string (u8-list->bytevector '(99 97 102 101)))
⇒ "cafe"

(string->utf8 "café") ;; SMALL LATIN LETTER E WITH ACUTE ACCENT
⇒ #vu8(99 97 102 195 169)

Scheme Procedure: string-utf8-length str ¶

C function: SCM scm_string_utf8_length (str) ¶

C function: size_t scm_c_string_utf8_length (str) ¶

Return the number of bytes in the UTF-8 representation of str.

Scheme Procedure: string->utf8 str ¶

Scheme Procedure: string->utf16 str [endianness] ¶

Scheme Procedure: string->utf32 str [endianness] ¶

C Function: scm_string_to_utf8 (str) ¶

C Function: scm_string_to_utf16 (str, endianness) ¶

C Function: scm_string_to_utf32 (str, endianness) ¶

Return a newly allocated bytevector that contains the UTF-8, UTF-16, or UTF-32 (aka. UCS-4) encoding of str. For UTF-16 and UTF-32, endianness should be the symbol big or little; when omitted, it defaults to big endian.

Scheme Procedure: utf8->string utf ¶

Scheme Procedure: utf16->string utf [endianness] ¶

Scheme Procedure: utf32->string utf [endianness] ¶

C Function: scm_utf8_to_string (utf) ¶

C Function: scm_utf16_to_string (utf, endianness) ¶

C Function: scm_utf32_to_string (utf, endianness) ¶

Return a newly allocated string that contains from the UTF-8-, UTF-16-, or UTF-32-decoded contents of bytevector utf. For UTF-16 and UTF-32, endianness should be the symbol big or little; when omitted, it defaults to big endian.
