I have added a lot of new references to my .bib file, which I got from online portals like sciencedirect.com.
I'm managing my .bib file with
My bib file was encoded in latin1 (CP1252), because that worked well with my latex setup.
No with the new references I could not save my file any more because the encoding CP1252 can not display the following characters
I then tried to save it in UTF8, which for sure worked well, but produced a lot of problems with my latex setup: if I understood correctly, I then have to use
biblatex backend and I had endless problems with compiling and was not able to get a working pdf file in the end. :-(
I even tried to change all my .tex files to utf8 as well to match them with the .bib files, but still I get errors with biber. (One idea: I have some fields "annotate" with very much text in there, which might cause problems.)
So I want my CP1252 encoding back but I don't know how to find the problematic characters in my .bib file and replace them by something which CP1252 can process.
How can I identify the records with the problematic characters and replace those? The bibtex file is very large (thousands of entries) and I don't see how to solve that, I've already lost hours of my (very short) time and don't see any hope.
