® ™ and other non standard characters

Hi
Having a bit of a problem with ® ™
After uploading Excel.xls data via Navicat to mysql, all ® ™ chatacters display correctly in Navicat.
However when viewing in PHP runner - I see additional characters (attached jpg)
When I edit out the extra characters in PHP runner, the data in that field becomes invisable to Navicat - eek -

Thanks

Peter
