John, btw:
regardless which browser used, sometimes it happens in an unregular pattern, that the gsearch.php searches for "ISO-8859-1". Seems something in the link before that is misformatted, misinterpreted or misunderstand from this link part

May be you have an idea and if you can spare the time have a look into it, if others can confirm that on their sites. Not a big deal though, happens in average each 5-15th request so it doesn?t bother me much.
