LyX will handle Unicode BibTeX files properly, but only if the encoding of the document is set to the same as the encoding of the BibTeX file. I.e., LyX assumes that the encodings of the two files are the same, because that actually needs to be the case for processing purposes. There are newer processors, such as biber, that will do Unicode, and the newer BibLaTeX processor will do this, but for the standard LaTeX + BibTeX combination, you really need to use pure ASCII, because that is all BibTeX supports. You can sometimes get away with a bit of Unicode in a BibTeX file, actually, but it's just sheer luck when it works.
Ideally, LyX would detect the encoding of the file and re-write it as needed. But this is impossible to do reliably, in principle, and it is difficult to do with much reliability in practice. See: http://www.lyx.org/trac/ticket/6223. Richard
