This means that once a tuple has been created, its elements may not be changed, removed, appended or inserted. It is declared using parentheses and comma- separated values.

There are two aspects to this problem: Knowing the encoding of the source file: calibre tries to guess what character encoding your source files use, but often, this is impossible, so you need to tell it what encoding to use. This can be done in the GUI via the Input character encoding field in the Look & Feel- > Text section of the conversion dialog. The command- line tools have an ebook- convert- txt- input- -input- encoding option. When adding HTML files to calibre, you may need to tell calibre what encoding the files are in.
To do this go to Preferences- > Plugins- > File Type plugins and customize the HTML2. Zip plugin, telling it what encoding your HTML files are in.
Now when you add HTML files to calibre they will be correctly processed. HTML files from different sources often have different encodings, so you may have to change this setting repeatedly. A common encoding for many files from the web is cp.
I would suggest you try that first. Note that when converting HTML files, leave the input encoding setting mentioned above blank. This is because the HTML2. ZIP plugin automatically converts the HTML files to a standard encoding (utf- 8). The first thing to realize is that most ebooks have two tables of contents.
One is the traditional Table of Contents, like the To. C you find in paper books.
This Table of Contents is part of the main document flow and can be styled however you like. This To. C is called the content To. C. Then there is the metadata To. C. A metadata To. C is a To. C that is not part of the book text and is typically accessed by some special button on a reader. For example, in the calibre viewer, you use the Show Table of Contents button to see this To. C. This To. C cannot be styled by the book creator.
How it is represented is up to the viewer program. In the MOBI format, the situation is a little confused. This is because the MOBI format, alone amongst mainstream ebook formats, does not have decent support for a metadata To. C. A MOBI book simulates the presence of a metadata To. C by putting an extra content To. C at the end of the book. When you click Goto Table of Contents on your Kindle, it is to this extra content To.
C that the Kindle takes you. Now it might well seem to you that the MOBI book has two identical To. Cs. Remember that one is semantically a content To.
C and the other is a metadata To. C, even though both might have exactly the same entries and look the same. One can be accessed directly from the Kindle’s menus, the other cannot. When converting to MOBI, calibre detects the metadata To. C in the input document and generates an end- of- file To. C in the output MOBI file. You can turn this off by an option in the MOBI Output settings.
You can also tell calibre whether to put it and the start or the end of the book via an option in the MOBI Output settings. Remember this To. C is semantically a metadata To. C, in any format other than MOBI it cannot not be part of the text. The fact that it is part of the text in MOBI is an accident caused by the limitations of MOBI. If you want a To.
C at a particular location in your document text, create one by hand. So we strongly recommend that you leave the default as it is, i. Also note that if you disable the generation of the end- of- file To. C the resulting MOBI file may not function correctly on a Kindle, since the Kindle’s use the metadata To.
C for many things, including the Page Flip feature. If you have a hand edited To. C in the input document, you can use the To. C detection options in calibre to automatically generate the metadata To.
C from it. See the conversion section of the User Manual for more details on how to use these options. Finally, I encourage you to ditch the content To. C and only have a metadata To. C in your ebooks. Metadata To. Cs will give the people reading your ebooks a much superior navigation experience (except on the Kindle, where they are essentially the same as a content To.
C). Note. The newer AZW3 format has proper support for a metadata To. C. However, the. Kindle firmware tends to malfunction if you disable the generation of the. To. C. So it is recommended that you leave the generated.
To. C alone. If you create an AZW3 file with a metadata To. C and no. end- of- file generated To. C, some features on the Kindle will not work, such.
Page Flip feature. This is caused by a bug in the Amazon software. You can work around it by going. Preferences- > Output Options- > MOBI output and setting the “Enable sharing. If you are reconverting a previously converted book.
Note that doing this will mean that the generated MOBI will show up under. Books on the Kindle Fire and Amazon whispersync. It’s your choice which functionality is.
