Require or disallow the Unicode Byte Order Mark.

The fix option can automatically fix all of the problems reported by this rule.

Under "always" a CSS file whose first node is a @charset, in any spelling, gets a warning about the option rather than a mark: the mark outranks the encoding declaration behind it, so set "never" or leave the rule unset for such files, and let Stylelint's at-charset-rule-no-invalid rule judge the declaration's spelling. An SCSS or Less file gets the mark as any file does, since neither compiler carries it into the output.
