It is probably due to a database configuration, you should give these steps a try to see if it helps to clear things up:
1) Make sure the database could support the characters by going to mysqladmin and running the query:
alter database [enter your database name]charset=utf8;
ALTER TABLE pg1_gallery_images CONVERT TO CHARACTER SET utf8;
2) Add this line to the bottom of the connection file (/Connections/your connection file name.php) :
mysql_set_charset('utf8',$your connection file name);
