There are some web servers in the wild that can serve static files with an

incorrect encoding (e.g. https://bz.mercurial-scm.org/show_bug.cgi?id=6559).

One way to prevent any issues is to not use any non-ASCII characters, e.g.

URL-encoding them or using HTML entities.

check charset of all tracked files ending in .js

  $ cd "`dirname "$TESTDIR"`"

  $ testrepohg locate 'set:**.js' \
