I have a citation where the author has the first name Angélique. The citation key in the text shows (Angélique M Lastname et al., 2001). It shows up properly in the PDF output. I also have a bibliography item with a Unicode character in the title. When I view it within the citation dialog, it shows up as multiple incorrect characters. Again, it shows up properly in the PDF output. The display font in LyX is one that has a full set of Unicode characters. I am using 1.5.0rc1 under Windows XP. The bibliography is set to Natbib mode.
