I have a bibtex file entry with a URL field so:

url = {{http://links.jstor.org/sici?sici=0025-570X\%28198912\%2962\%3A5\%3C291\%3AHRATQS\%3E2.0.CO\%3B2-8}}

where I have manually escaped each percent sign with a backslash.

It compiles correctly with biblatex/biber but the resulting hyperlink in the document still has the escaped percentage sign and does not link correctly to the website.

Is there a workaround for this problem?

Thank you.

You don't have to escape the %, the url field is printed verbatim, so there won't be a problem. Hence, just remove the backslashes before the percentage signs.

Thanks. That did the trick. I will check before I ask in future :-) – chandra Jun 11 '11 at 19:41
@chandra: You should also remove the second pair of braces at the start/end of the URL field. These braces would also be printed verbatim, resulting in a non-functional link with the hyperref package. – lockstep Jun 11 '11 at 19:47
Thanks, @lockstep. I did not realize it, but I had removed the extra brace pair when I got it working. – chandra Jun 13 '11 at 5:38
I just want to add that for my configuration (LyX / MiKTeX 2.9) I do have to escape the URL. The citation style is based on "annotation.bst". I guess there are customisations in there, that are not compliant. So just in case anyone else has problems in that area: it is not neccessarily the case that urls are printed verbatim. – Mene May 16 '15 at 21:19
@Mene This question was for biblatex/biber, where my answer applies, AFAIK. You are using bibtex which is a completely separate system for dealing with bibliographies. – Torbjørn T. May 21 '15 at 13:47
