Bug in Kindle's lookup?

[sevenkul]

While I was struggling with lookup errors in Kindle, I encountered a strange problem. I simplified the files I was working on and upladed here. There is a simple dictionary and a simple book of which languages were marked as French for the sake of formality.

The curious thing here is that Kindle Paperwhite can't find any definition for the first "istimaline" but it can find the definition for the second "istimaline". I couldn't find any difference between two strings. Is there anyone who have an explanation for this or is this a bug?

I tried it only on Paperwhite.

I couldn't test your original files, because you set the language code to French and I didn't want to uninstall my French dictionaries.
However, after changing the language codes and re-creating the .mobi files with KindleGen 2.8, the lookup worked fine in both lines:

book.opf

<dc:Language>tr</dc:Language>

dictionary.opf

<dc:Language>tr</dc:Language>
<DictionaryInLanguage>tr</DictionaryInLanguage>
<DictionaryOutLanguage>tr</DictionaryOutLanguage>

Try changing the language codes. If that doesn't fix your problem, it's indeed a PW bug.

BTW, since older Kindles select dictionaries based on the <dc:Language> value of the ebook, you may want to use the proper language codes both for books and dictionaries. Though not strictly necessary, I'd also recommend using the same value for <dc:Language> and <DictionaryInLanguage> in dictionaries. This will allow non-native dictionary users to look up words used in definitions.

I thank you for your interest in the problem. The language tr or fr didn't make any difference on my PW. I set the language to fr with the assumption that it is not so common. In fact, I couldn't find an original language code other than en, tr, fr which Kindle Previewer accepts.

So, you tested lookup in a different device, didn't you?

I tested it on my K3 and it worked fine with the Turkish language codes.
