Easy-Deflate

Library for compressing and decompressing strings in JavaScript, feature full Unicode support and is compatible with most browsers.

Use:

Copy the script inclusion from demo.html.
Call deflate(foo) in order to compress a string.
Call inflate(bar) in order to decompress a string compressed in this manner.
Both functions return a string, or null in case of illegal input.

The compression works by first UTF-8 encoding the input, then compressing it to a raw deflate stream. The stream is then base64 encoded, and finally the identifier "rawdeflate," is prepended.
