There is hardly any point using your util as long as it does not get rid of the 200 character limit... Its not meaningful to work with cut-off notes.
Here is the source code to get rid of the 200 char limit:

And if you are brainy enough, maybe you can use it to remove the limit on .pdf as well. This only works for .epub
Have fun.
