I have the following URL
http://www.wolframalpha.com/input/?i=density+destilled+water+23°C
Trying to insert this as a \footnote with \url I got an error. The same with
\footnote{\url{http:// [...] 23^{\circ}C}}
I hope you can help me!

When URLs contain special characters, and you want to use them in an argument (even in a moving argument), the standard approach is yo use \urldef. Below I give to two options:
Use
\urldef:\documentclass{amsart} \usepackage{hyperref} \urldef{\wxxiii}\url{http://www.wolframalpha.com/input/?i=density+destilled+water+23°C } \begin{document} \footnote{\wxxiii} \end{document}The resulting footnote:
Use
http://www.wolframalpha.com/input/?i=density+destilled+water+23%C2%B0C(which you can get with the help of your browser) and
\urldef:\documentclass{amsart} \usepackage{hyperref} \urldef{\wxxiii}\url{http://www.wolframalpha.com/input/?i=density+destilled+water+23%C2%B0C} \begin{document} \footnote{\wxxiii} \end{document}The resulting footnote text:

@giordano No. At least not for me using TeXworks' viewer, Evince, Acrobat Reader or Okular. In which PDF viewer do you get the wrong URL? Jun 14, 2015 at 17:38

Okular 0.20.2. The URL I get is wolframalpha.com/input/… Instead, TeXstudio viewer read wolframalpha.com/input/?i=density+destilled+water+23%EF%BF%BDC– giordanoJun 14, 2015 at 17:43

\url{http://www.wolframalpha.com/input/?i=density+distilled+water+23%C2%B0C}\urldefwill also have to be used.
