french diacritics (éèêàîû) do not appear in the lesson box (training) although they appear in the lesson text (edit lesson). (I think it is the same with Windows)

exemple of lesson text followed by the result:
Cette philosophie est composée de deux grands mouvements, l'existentialisme athée et l'existentialisme chrétien. Elle s'intéresse avant tout à la question du sens de l'existence.

Thank you for your post. To avoid that you have to type characters that are not supported by the current selected keyboard layout, we use a special filter to allow only specific characters. But, of course, you can change this setting for every layout:
Goto "General Setting" - "Language" and then click the button "Advanced". Here you can define all the characters you want to type. In your case you can add the french diacritics in the first list of characters. But not forget, these characters can not be displayed by the virtual keyboard while training.

Thanks for the precise answer (I think that I would not have found it by
myself).

Thanks for the program also.
