this happens on every link on a page (only on content inside the pages, never on other stuff like menus or other links), after the text there is this symbol <. I've searched my css with no results, it must be something in the code..
Preview (the "here" link has this strange < character):
Errata Corrige: before I stated this happens only in Explorer, that was a mistake. Sorry, it happens also on Firefox and Chrome.
