I wrote a [small shell script](https://github.com/Ryuno-Ki/Wicked-outer-World/blob/master/check_encoding.sh) so I can ensure the encoding before commiting easier. For now it only looks for /source/lib - I'll adjust it later.

        source/lib/accuracy.php: PHP script, ISO-8859 text, with CRLF line terminators
        source/lib/rendersidebar.php: PHP script, ISO-8859 text, with CRLF line terminators

The first one was touched by me, but the latter one is pure upstream, i.e. yours. Please check the encoding.
