Is there a way that Javascript can validate that text in a textarea is
UTF-8?

Is there a way that Javascript can validate that text in a textarea is
UTF-8?

Text in a textarea as far as JavaScript in the HTML document sees it is
just a string of characters where those characters in modern browsers
(where modern means Netscape 4.06 and later and IE 4 and later) are
Unicode characters. Only a byte stream could be tested to conform to a
particular encoding like UTF-8 so I don't think you question makes any
sense as script in a browser does not deal with byte streams.
