Bloom Reader alphabetical order

Hi,
I see that Bloom Reader is supposed to automatically alphabetize your books. That’s great! However, it seems like some characters throw it off. For example, it automatically sorts my books in the following order:

Huɛɲɔ̃
Hããsiekɔluwɔ
Nuɔ̃kɔ
Sɛ̃cɔ
Vasirɔ biɛ̃ŋɔ̃
Ɲĩbũmɔ

Is it possible to get it to sort nasalized vowels (ex. ã) and non-English letters (ex. Ɲ) according to the more accepted sort order, putting them at least somewhere near their “less exotic” counterparts?

Thanks!
Susie
