Error on PRC > EPUB conversion

[myusername]

I'm trying to convert a PRC document to EPUB and I'm getting the following error. Anyone have any ideas what is causing this to happen? Is there any way to put some debugging in there to find out exactly which strings are causing the "All strings must be XML compatible" error? This document is fairly large so I'm not even sure where to start looking. Any help would be very much appreciated.

I don't know what the cause of your problem is try checking the Transliterate Unicode characters to ASCII option under Preferences - Conversion _ Look & Feel.

Update: Darn you Kovid... sneaking in with the correct answer.

Thanks for that information, it appears that the .prc that MobiPocket is creating is not working in any other reader so definitely corrupt.

Actually, the only reason I was trying to convert from a .prc was an issue I'm having with calibre itself. I have a compilation of .htm files that I am trying to convert and am having a problem with the images appearing. If I convert one .htm file with all of the images in the same directory I have no problem. However, after building a table of contents with links to all of the other .htm files, everything works fine except that the images aren't showing. Is there something that I might be doing wrong?

In the debug, the image properties show that it is trying to load the image from the same debug folder -- would that mean that calibre is not including the images when it loads the table of contents?

Normally with multi-html books, all you have to do is drag the single toc html into Calibre and Calibre will look after the rest by zipping up all the referenced files (html, images, css).

[myusername]

Yep, that's what I did and it indexes everything perfectly but the images just won't load. Is there a setting that I'm missing somewhere?

[jackie_w]

If you look inside the zip that Calibre has created in your library, are the images present?

[myusername]

I didn't even think to do that! They definitely weren't in there but after adding them in everything compiles perfectly. Thank you!

Well I'm glad to have helped. However, you shouldn't have needed to add them manually. Odd.
