Duokan installs alongside the typical Kindle OS, so you can dual boot to it as well. Nearly every Kindle model can run Duokan (even the Kindle DX).
The third line of defense is to install Duokan, an alternative operating system for the Amazon Kindle which is designed specifically for the Chinese language.
The Kindle devices all support Chinese characters ( except for the Kindle DX but if you have one of those, look at the 3rd option). If you are facing any of these problems, hopefully this can help! While we are no experts, we have worked with a number of our customers on these issues and have found some common solutions. Frequently, the Chinese characters will show up as rows of boxes with question marks, or even more insidious, about 90% of the characters will display properly with the rest displaying as boxes. We frequently get emails from our readers asking for Chinese language support why their Kindle, Kobo, iBooks, or other e-reader device is not displaying characters.
If this has happened to you, do not fret, you’re not alone. You open it up and to your horror you see this.
