Ebook-convert creates unreadable epub if there's a hash in the filename

Bug Description

If I use ebook-convert to create an epub from an HTML file with a # in the filename, I get messages like:

Removing fragment identifier u'1.html#toc0' from TOC as Adobe Digital Editions cannot handle it

The generated file fails epubcheck, and my iPhone can't open it. If I remove the # from the filename and run it again, it generates a valid file.

I'm using the version that came with Calibre 2.55 on Ubuntu.

Not a major bug, but took me a few hours to figure out why some files would convert with no problems and this particular file wouldn't.

I cannot replicate this with the current calibre release. Creating an
HTML file test#foo.html with the contents:
<!DOCTYPE html>
        <meta charset="utf-8" />

and converting ti with ebook-convert results in a file that has no
errors as per epubcheck and filename related warnings during conversion.
I dont have an iPhone to test on, so I cannot say whether it will work
on one or not.

That said, I will change the HTML input to replace # in filenames with _

Fixed in branch master. The fix will be in the next release. calibre is usually released every Friday.
