Unicodify start-tor-browser.desktop comment ("−1" not "-1")
This patch makes it use the proper Unicode minus sign U+2212 instead of the ASCII approximation U+002D.
I don't have a build machine available at the moment, so I haven't tested the patch. https://specifications.freedesktop.org/desktop-entry-spec/latest/ar01s03.html says "Desktop entry files are encoded in UTF-8" so the non-ASCII character shouldn't be a problem.
