Accept-Charset

Warning

Do not use this header. Browsers omit this header and servers should ignore it.

The Accept-Charset request HTTP header was a header that advertised a client's supported character encodings. It is no longer widely used.

UTF-8 is well-supported and the overwhelmingly preferred choice for character encoding. To guarantee better privacy through less configuration-based entropy, all browsers omit the Accept-Charset header. Chrome, Firefox, Internet Explorer, Opera, and Safari abandoned this header.

Today, Accept-Charset is most notable for being one of several forbidden header names.

Header type Request header
Forbidden header name yes
