Hi, The subject pretty much sums it up. As suggested in previous thread I've upgraded to lyx 2.2. The new version would not produce a result when exporting to PDF because of unknown characters. I've tracked this to Croatian diacritics from the references bib file. I've manually replaced all surnames with diacritics I. E. Č to C or ž to z and than it worked fine. Although the names were no longer correct.
Any idea what is happening here and what to do? Thanks
