DB interactions - Unknown character inserted in database.

hi,
I am developing an application where I have to insert data via a wysiwyg editor(tinymce) to the mysql database.

I am inserting data with mysql_query() function and filtering the data with mysql_real_escape_string().

Everything is working fine, the required data is properly,the html etc.

But the problem is when I am giving enter or space in the editor and inserting it to the database the record is showing unknown character  in their place.

Please help me in this regard ASAP.

Thanks anyway for the replies.
