Clara Arabic and dictionary

[ofai]

Hi
I am trying to learn Arabic and I think that reading it with my Kobo would be very useful if I could translate the words I don' t know directly from an internal dictionary.
Then, to do this ,I went to internet and where able to install Arabics Ebooks and a dictionary.The text now is beautiful but my first concern is that the hyperlinks don't work properly, and I cannot translate.
The line under the word I need to translate ,when touched , don't show or don't beging at the begining of the word and don't finish at its end. And I cannot move the circles limiting the line. Only the words with two letters maximum can be translated.
Could you help me resolve these problems? I didn' t find anything about it on internet.
Thank you very much

I read with a Kobo Clara
From the site cooltext , I downloaded and installed the arabic typesetting : arabtype.ttf
From the site Hendawi, I downloaded ebooks epubs.
From MobilRead,I downloaded the dictionary ditchtml-ar-en.zip , copied it in the folder dict of the kobo , with the name ditchtml-nl.zip .
PS: Second problem, but this one a little one, there is no front cover to the books.
