What if your 100 characters stops with some tag still open, or multiple tags still open -- e.g. in the middle of a cell of a table? In general, you can't solve this. How should those tags be closed again? You could in theory have a naive solution that just closes all opens tags, but there's no guarantee this will be appropriate. The only way I can think to do this is strip the HTML, then slice. Also, remember that Django currently uses bytestrings internally (default UTF8), so you might want to decode into unicode strings before slicing, then re-encode.
