character encoding conversion without other changes?
I use Sigil for most changes I want to make to any of my files. But occasionally I still resort to Calibre conversion when I get something with a non-UTF character encoding. Usually when this happens, I'm not changing the file type, just going from one epub to another epub.
Ideally I'd like the file to look the same afterward, with all the font sizes the same and page layouts etc... Mostly they are, but some of the margins get changed, and some of the font sizes. Can someone suggest how I should have the settings configured to get as close as possible to the appearance of the original file?
