Results of your files:
1. The little "u" fill the whole screen in Calibre, the mobi version.
2. The epub version shows up nice.
3. Amazon don't accept epub, but the mobi file are nice.
4. Duokan mobi - don't show images ( not supposed to ) but - you are correct, missing letters.
5. Duokan epub - show the images - but fail to show the text.
6. For both, the last test character is "spacy".
----------------
Here is my excuse for being so slow in understanding this:
- I don't have any German or Norwegian books. And for several available, when Calibre did thing like it did with your mobi file - I blamed the source.
The spacy letters are due not using "spacing modifier letters". I am unsure how to classify it. It shows the character, but not exactly in a nice way. But the missing character are much more serious. Tested K3 and DXG, same results, while
mobi don't show on the last, according to specifications. I made a similar test case in Norwegian - and the font table or the program are faulty.Which ?
Both it turned out. My crazy writing - is in fact duokan font files running on the computer. I wanted to feed character codes, and started to wonder where you found those German "umblauts" - Highly surprised, never knew the keyboards were so much different. In the test case - all system fonts are duokan. No other fonts allowed. Then using german input..
On top of this, a lot of faults turned up with the 2012 release, which also removed the Beijing Founder fonts, which I would expect to be more reliable.
@curstpriest - yeah, yeah, I cannot argue with you, honey

- except, if Amazon had everything covered, we would not do any of this. We would find something else to hack and modify, right ? I am the owner of several kindles now, not for reading, but for hacking !

And Amazon are probably laughing
