Chinese ebook conversion problem

kevin_y · 03-18-2016, 10:00 PM

I have a HTML document in Chinese that I input into Calibre to create EPUB and MOBI ebooks. The resulting ebooks can be read on my desktop Windows PC: both the Windows Kindle software and Calibre's built-in EPUB reader display the Chinese font properly. Then I send the MOBI to the Android Kindle reader on my Galaxy Note 3 smartphone, and it, too, displays the Chinese font correctly. Now, here is the problem. When I send the EPUB file to the Android "Aldiko" epub reader on my Galaxy Note 3, it shows "squares" instead of Chinese font. Now, before you think this is Aldiko's problem, here is the thing. If I extract the HTML files inside the EPUB, open them up with a text editor in Windows, and change the HTML tag from this:

<html xmlns="http://www.w3.org/1999/xhtml">

to this:

<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="zh-CN">

THEN ALDIKO WILL DISPLAY THE CHINESE FONT PROPERLY!!

So here is my question. Can I configure Calibre in such a way that it will create the HTML tag accordingly in the EPUB file? Is this a Calibre problem at all? Or should I talk to the Aldiko developer instead?

Thanks in advance to all!

You need to talk to the aldiko developer. EPUB reading system need to use the language spedified in the opf file when it is not specified in the html file.

In any case if you want to have that attribute in the epub file, you can either add the lang attribute to the input html file, or just open the epub file in the calibre editor and add the lang attribute yourself.

You can also use the search and replace feature in the conversion dialog to replace

<html

by

<html lang="whatever"
