Attribute value

Value Description
character-set

Character encoding list used for form submission, separated by spaces or commas.

Common values:

  • UTF-8 - Unicode character encoding
  • ISO-8859-1 - Character encoding for Latin letters

In theory, any character encoding can be used, but no browser can understand all encodings.

The more widely a character encoding is used, the greater the chance that the browser will understand it.

To view all available character encodings, please visit ourCharacter Set Reference Manual.
