Prepare a string for use as a valid CSS identifier (element, class or ID name). This function is similar to a core version but with more sane filter values.

http://www.w3.org/TR/CSS21/syndata.html#characters shows the syntax for valid CSS identifiers (including element names, classes, and IDs in selectors.)

Parameters

$identifier: The identifier to clean.

$filter: An array of string replacements to use on the identifier.

Return value

The cleaned identifier.

  // - A-Z (U+0041 - U+005A)
  // - the underscore (U+005F)

  // We strip out any character not in the above list.
