[lhuxley]

I am converting a rather ancient book to ebook format using Calibre. I would like to preserve the hypens in the text for historical reasons. I'd also like the text to reflow normally. The obvious choice would be to replace the original hyphens with soft hyphens. However soft hyphens are invisible in the main editor window.

Is there any way to make soft hyphens visible? I've tried changing the font but that doesn't work.
