Garbage (extra whitespace returns, etc.) in mysql

for some reason, my database is getting newlines and spaces, etc. after the image names in a certain column (was a varchar, switched it to char), like this:

upload/Nte1282160654.jpg%20%20%20%20%0D%0A%20%20%20%20%0D%0A%20%20%20%20%0D%0A%20%20%0D%0A%0D%0A

( this is what i get after checking the utf8 encoding )

i need to strip this garbage out so i can get ahold of a valid URL to this image.

i tried doing this:

$pic = trim($entryPic);

in the php script that inserts the post value into the db, but no dice… any ideas anyone?
