I must butt in once more - this is a very good point. Not many authors pay attention to the grammatical aspect of foreigners' English. I should imagine that Viktor would have trouble using articles, for example, and as for Fleur - isn't the word order in French a bit different from English? It'd be interesting to see an author try and reproduce some more imaginative markers of second-language English. Of course, that can be difficult if English is their first language, but still.
