Can't use Nordic characters for book names (æ, ø and å)

There are already some Nordic Bibles in Accordance. With the upcoming release of Danish Bibles (along hopefully Norwegian or Swedish at some point), the characters æ, ø and å doesn't seem to be supported in the book names, abbreviations and searching.

In the screenshot below “Hojsangen” is supposed to be “Højsangen”

According to email correspondance with André, this is a bug. Is there a point, when we are to except a fix for this?
