The following demo shows the BOM byte and it is highlighting as error: http://pygments.org/demo/59241/

The file is also attached here.

    In the Lasso lexer, I've gotten around this by having get_tokens_unprocessed strip the BOM out beforehand (though that change hasn't been pulled in yet).

    text = text.lstrip(u'\xef\xbb\xbf\ufeff')

    Thanks for your info!

    However it sounds to be not the "right" place to put the fix. The BOM should be removed before passing to the lexer, but get_tokens_unprocessed is call after the lexer tokenized the input. Also it is bad idea to put the fix in all lexer classes.

    I know it's a hack; ordinarily I'd have ignored the issue, except that BOM-prefixed files of Lasso are common since earlier versions of it required the BOM to read a file as UTF-8. Hopefully this gets fixed upstream so I can take that line out.
