Localizations and character encodings
Browsers process text as Unicode internally. However, a way of representing characters in terms of bytes (character encoding) is used for transferring text over the network to the browser. The HTML specification recommends the use of the UTF-8 encoding (which can represent all of Unicode), and regardless of the encoding used requires Web content to declare that encoding.

Using FormData Objects
The FormData object lets you compile a set of key/value pairs to send using XMLHttpRequest. It's primarily intended for sending form data, but can be used independently from forms in order to transmit keyed data. The transmission is in the same format that the form's submit() method would use to send the data if the form's encoding type were set to "multipart/form-data".
