Does not work with UTF chars

[tmorehouse]

simple workaround:

    var b64str = $.base64.encode(unescape(encodeURIComponent(string_to_encode)))

This will breakup UTF8 chars into their component bytes and then pass to to the base 64 encode routine. unescape is not UTF8 aware to it treats each % encoded byte as a single character.

window.atob() requires the same workaround.

Although unescape is deprecated, and may start to disappear from modern browsers (ref https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/unescape)

Oh, this is a shame! I was going to use for utf and I got the same error

I wish I'd seen this earlier, it would've saved me some trouble. :(

I wound up using the suggestions in the following stackoverflow question.
http://stackoverflow.com/questions/246801/how-can-you-encode-to-base64-using-javascript

(Since there is a whole source code + multiple suggestions on how to implement base64 in javascript there, I simply cut-and-pasted to get all of the goodies in one file.)
