The Document.characterSet read-only property returns the character encoding of the current document. The character encoding is the character set used for rendering the document, which may be different from the encoding specified by the page. (The user can override the encoding.).
The properties document.charset and document.inputEncoding are legacy aliases for document.characterSet. Do not use them anymore.
Syntax
var string = document.characterSet
Examples
<button onclick="alert(document.characterSet);">Show character set</button> // returns document's character set, such as "ISO-8859-1" or "UTF-8"
