What encodings are available Node.js

Question

I'm trying to figure out what encodings are available in node.js.

The documentation (http://nodejs.org/api/buffer.html#buffer_new_buffer_str_encoding) says:

Allocates a new buffer containing the given str. encoding defaults to 'utf8'.

but nowhere is specified a list of available encodings. Maybe I missed it.

I'm working on script which should be able to output in wide range of encodings. So far I know only about utf8 as doc is saying :)

Thx, Jaro.

Encodings available in Node.js:

• ascii: For 7-bit ASCII data only. This encoding is fast and will strip the high bit if set.
• utf8: Multibyte encoded Unicode characters. Many web pages and other document formats use UTF-8.
• utf16le: 2 or 4 bytes, little-endian encoded Unicode characters. Surrogate pairs (U+10000 to U+10FFFF) are supported.
• ucs2: Alias of utf16le.
• base64: Base64 encoding. When creating a Buffer from a string, this encoding will also correctly accept "URL and Filename Safe Alphabet" as specified in RFC 4648, Section 5.
• latin1: A way of encoding the Buffer into a one-byte encoded string (as defined by the IANA in RFC 1345, page 63, to be the Latin-1 supplement block and C0/C1 control codes).
• binary: Alias for 'latin1'.
• hex: Encode each byte as two hexadecimal characters.
