Kovid,
I'm having some difficulty with conversion from HTML to ePub using Calibre. I am converting copywritten articles for an author friend of mine from HTML format to ePub, with his authorization. I am having pretty good success with most of the usual issues concerning the conversion, but when I get to the copyright symbol at the end of his article, it is being translated into something other than a small 'c' inside a circle. It looks like a capital 'S' with an accent over it. Not sure what the name of that symbol is, but it isn't what I am after.
How can I direct Calibre to preserve the copyright symbol? The symbol is correct in HTML, it just gets translated into that 'S' when the document goes from HTML to ePub.
