i'm relatively new to latex, so forgive me, if thats a silly one: I'm using miktex and texstudio. I keep getting the following error message, which prevent me from building up or compiling a document
"inputenc: Keyboard character used is undefined(inputenc) in inputencoding
inputenc: Keyboard character used is undefined(inputenc) in inputencodinglatin1'. \newblock Développement par compression de l"
They first appeared, when i first cited a certain reference. I understand they are due to certain characters in the .bib file. So i changed the characters in the .bib file with jabref. That didn't work, then i deleted those citations from my document, didn't work either. Now i even started to build up a new .bib file, in which i type everything by hand. But even with that one and all citations removed, i keep getting this error message. Anyone any ideas? Thanks!!!
