The HTTP header can set the character encoding of a style sheet.
The HTML page is served as UTF-8 and has a class name ÃœÃ€Ãš. This only matches the sequence of bytes in the selector of the CSS file if the selector is read as ISO 8859-15. The CSS file encoding is established as ISO 8859-15 using only the HTTP header.
Text as read from the style sheet: (if blank, the style sheet hasn't been read at all)
