 Initialize hs_init with UTF8 encoded arguments on Windows.

 Summary:
 Get utf8 encoded arguments before we call hs_init and use them
 instead of ignoring hs_init arguments. This reduces differing
 behaviour of the RTS between windows and linux and simplifies
 the code involved.

 A few testcases were changed to expect the same result on windows
 as on linux after the changes.

 This fixes #13940.
