I had a problem with the automatic application of either title or sentence case on my non-english references. Therefore I added the language field of a reference as its language ID to the BibTeX export. This way the bib files could be identified as english or not and the respective cases were only applied to the english entries.
Figured I post this export style here, if someone would run into a similar problem.
