Thank you for your feedback on the translation. Translations are created by community members, so feedback is often very important.

As for the mixture with French: the translator may have forgotten to replace the example in French.
As for the text not fitting on the pages: at the moment, this is an incorrigible problem, because words in German and other languages are longer than English. But there is no point in making the font very small, and it is currently impossible to layout the book for each language separately.
