To me this sounds analogous to inserting tons of <space><backspace>
sequences into a string and expecting the software to automatically figure
out that they cancel. It would be possible, but it would probably add a
lot of overhead and it doesn't seem to be requested a lot. The best
solution is probably to fix your data. Unless you can point to a Unicode
standard that states that such cancellation should happen.
