I found utf8 based bibtex works in XeTeX, even BibtexKey in utf8. But Lyx did not support it good when cite more than one items. the latex source code show that the utf8 bibtexkey will be escaped. How can I cancel this escape?
I test in both linux and mac: OS: archlinux 3.2.6-2 TeX: texlive 2012 bibtex: 0.99d Lyx: 2.0.2 OS: Mac OS X 10.7.3 TeX: MacTeX 2011 Lyx: 2.0.2
