Named entities present error. Sigil to Calibre.

leftright · 02-19-2016, 10:35 PM

I first edit the book in Sigil, run a error check in Sigil, no faults.
Open the same book in Calibre's Editor, Bug check returns "named entities present" errors.
Auto fix in Cal-Editor, ok. Bug check again, no faults.

If I re-open the same book in sigil and repeat the above I get the same errors Evident in Cal-Editor.

Why'm I getting these errors ?.

Below is the error snapshot.

Because Sigil makes changes to your book, simply by opening it. Presumably, re-inserting named entities is one of those changes.

Thanks for your prompt reply.

I'm just curious as to why Calibre-Edit flags something which isn't flagged in Sigil, If it's ok for Sigil surely it should be ok for Cal-Edit ?.

Either Sigil is wrong or Calibre, which do I trust?.

I apologise for flogging a dead horse.

The reason calibre flags them is explained right there, in the check book panel.

Sigil (well not actually Sigil, but epubcheck) performs only spec compliance checks that are mostly useless. calibre checks for things that have been known to cause problems in actual real world usage.

Neither are WRONG.

The devices are ALL Spec non-compliant in someway. (Just go down to the EPUB forum Stickies and read them People like Hitch will have employment for a long time to come)

The originator of Flightcrew was a Spec purist

Spec is King.

Kovid is more practical. The End Goal is important., It works on the Reader.
Just (help) make it work on common devices by flagging known issues.

BTW, the Sigil preserve entities preference can be set to use numeric entities if you so desire to make it more like what calibre prefers and to make it easier to go back and forth if you want.

You Sir, are a mind reader. That's exactly what I need.

I prefer Sigil for major text editing and formatting as it's more user friendly, then I conclude editing with a bug check in Cal-editor as that's my primary repository and library for all devices.

Thanks.

Edit: I searched and I found this, but I have no idea what to do with that or if that's what I need.

Edit ==> Preferences ==> Preserve Entities (tab)

Add the entities you want to the list.

...

calibre by default likes to turn everything into unicode, in addition to nuking doctypes (because you can do just fine without them). For calibre, functionality is the chief goal. As a tool used heavily by endusers, this makes sense.

Sigil puts more focus on following the IDPF rules and making spec-compliant EPUBs. As a tool used heavily by ebook producers, this makes sense too.

The two objectives have been known to clash.

The calibre error check is great, and it is equally great to blithely ignore its endless "named entities present" warnings.
