Adding a calendar fails when the given name contains special characters on Windows

[huljar]

I have tried adding my personal calendar from the hosted exchange of my organization. However, when I gave it a name containing a German umlaut ('ö' in this case), adding the calendar after completing the wizard failed with the following error message:

roughly says: An error occurred while adding the calendar with address ... It will not be available.

When I replaced the 'ö' with 'oe', everything worked fine.

• TB version: 60.5.3
• Lightning version: 6.2.5.3
• ExchangeCalendar version: 5.0.0-alpha3
• OS: Windows 10

I remember doing the same thing on Linux (Debian stable) and this problem did not occur; using 'ö' worked fine.

@huljar Please check if the changes in #279 fix this issue.

I can confirm that #279 fixed the issue for me. It's working perfectly now! Currently using TB 60.7.0 and Lightning 6.2.7. Thanks :)
