Did you test this? I'm fairly sure this doesn't work correctly. String is immutable so calling the method replaceSpecialCharactersToBibtex without assigning the returned string to 'value' variable shouldn't do anything. Two other things too: The \ escapes and makes it possible for the quotation marks to be used, but if I understood correctly from quickly reading Bibtex docs (I might be wrong though), it needs a backslash to be in the bibtex file too. So using only one backslash isn't enough, but in the method there needs 3 of them (one to escape the quotation mark, one to be actually shown in the string, and one to escape that blackslash) so that they go to the bibtex file correctly .\r also causes a line change which I'd guess isn't quite the correct one to use for the letter å.

But that's alright. Since we have the client meeting quite soon I'll merge, make the necessary fixes (you have the right idea there so fixes are pretty small) and write some tests to make sure it works.

Taking my words back a little (having discussed with you elsewhere). You can fix it later and we'll confirm in the client meeting how it's supposed to go, since there seems to be a little bit of conflicting information on the special letters (for example BibTex.org vs LaTeX Stack Exchange
