I'm pretty sure that's what it's doing. The character has to be stored 
somewhere, because if you remove the imagesource, the original character 
comes back.

Custom sort functions are made for this stuff. I'd test for the column 
the user wants to sort on, and sort normally unless it is the ratings 
column. In that case, use a custom function:

sort lines of fld <dataFld> by customSort(each)

function customSort pRatingHTML
   put 0 into tSkip
   put 0 into tNum
   repeat
     put offset("star",pRatingHTML,tSkip) into tOffset
     if tOffset = 0 then exit repeat
     add 1 to tNum
     add tOffset to tSkip
   end repeat
   return tNum
end customSort
