Accented characters are not displayed correctly in the italian translation of the installation program.
It's probably a wrong encoding in the italian translation. Will be fixed with updating our build system to buster and NSIS-3
Btw. mscomparin we do not have an italian translation for our Outlook plugin. If you would be willing to contribute one please get in touch with "email@example.com" I can happily send you the files needed and explain which tools to use / how it works. Its not hard.
