[Fixed] PAI installing to path containing foreign characters
As discussed yesterday in irc, the new PA.cInstaller 2.0 still has a problem for online installing to a path containing foreign characters.
One way to solve it was to run 7z.exe from $PLUGINSDIR, but this could potentially still give a problem if %USERPROFILE% contains foreign characters as well.
After some more investigation I found out that 7z.exe v9.14 beta also solves the problem. And, because this is not an issue for 99% of the users, probably it is better to wait for v9.14 to become stable and use that, before to change the installer script !
