I've run into another issue. The book has what is supposed to be alien speech and the author used << and >> as quotation marks. The << gets converted to << which CustomCleanerPlus seems unhappy with. After noticing this, I converted the << and >> to left/right guillemets ( « and » ) so not sure if the >> pair would also cause issues.
Code:
<p><b>The speaker to others replied <<corn dogs!>></b></p>
After running CustomCleanerPlus and saying yes to continuing:
Code:
<p><b>The speaker to others replied <
<corn dogs!="">></corn>
</b></p>
