Hyperref using the wrong language script for \url?

Question

In a mixed language document, I try to use a URL. Here is minimal input demonstrating

\documentclass{article} % compile with xelatex
\usepackage{hyperref}
\usepackage{polyglossia} 
  \setmainlanguage{hebrew} 
  \setotherlanguage{english}
  \newfontfamily\hebrewfont[Script=Hebrew]{Ezra SIL}% or{SBL Hebrew}
\begin{document}
  \begin{english}English separates Yankees and Brits?
  \url{http://www.google.com}
  \end{english}
\end{document}

Now, polyglosssia does not like this at all, complaining that:

! Package polyglossia Error: 
The current roman font does not contain the Hebrew script!
Please define \hebrewfont with \newfontfamily.

See the polyglossia package documentation for explanation.
Type  H <return>  for immediate help.
 ...                                              

l.9 \url{http://www.google.com}

I am confused. Didn't I switch to English on line 8?

Answer 1

If you change your link to \href{http://www.google.com}{Google} instead of using \url it works fine.

However, this doesn't actually solve the problem directly. Building on Leo's answer, but using polyglossia methods, (and LaTeX syntax) the correct solution is the following:

\renewcommand\UrlFont{\ttfamilylatin}

Answer 2

It has nothing to do with hyperref. \url uses \ttfamily as font. You get the same message if you simply call \ttfamily. At my opinion this is a bug in the font switching system of polyglossia. The script=hebrew option is still present after a language switch.

Answer 3

It's not a bug of url package. \url use \ttfamily by default, however, the default typewriter font lmtt is not for the default language Hebrew. Just redefine \UrlFont to fix it.

\def\UrlFont{\usefont{EU1}{lmtt}{m}{n}}
