2014-05-08 Solved a latex problem: The compilation failed. The Problem ap- peared when the bibtex file was added to the text. Actually, the text wasn't written in latex in the first go, but was a conver- sion of a Microsoft Word document. The bibliography data was ex- ported from Zotero. By cutting down the problem area, I discovered this character sequence \'\i in the bibtex file. (Meant was the letter `i' with an accent aigu.) When I removed the second pair of backslashes, it worked as expected. \'i is of the same pattern that is also used for accented variants of other letters. Is Zotero's export broken? http://marmaro.de/lue/ markus schnalke
