By running my LyX document I am getting this Package inputenc Error: Keyboard character used is undefined (inputenc) in inputencoding `latin9'
What is the best way to find the wrong character(s) in a bib file? The logfile before this error tells me Underfull \hbox (badness 1286) in paragraph at lines 1576--1576 \T1/ppl/m/n/10.95 cloud co-ver. \T1/ppl/m/it/10.95 Bi-ol, Rhythm Res. \T1/ppl/m /n/10.95 , I have checked the reference which contains cloud co-ver and have retyped all of its content, with no success (same error) perhaps somebody could check it or tell me how to check it myself: @ARTICLE{Cum02, author = {Cummings, D. R.}, title = {The seasonality of human birth, melatonin and cloud cover}, journal = {Biol. Rhythm Res.}, year = {2002}, volume = {33}, pages = {521-559} } Thanks again Wolfgang
