I have noticed a couple of things where Windows 10 does not support international the way I would expect a 2015 operating system to do. I have not found any solutions yet so any more info on these issues would be appreciated.

Compressed (zipped) folder

I tried to zip a folder in Windows 10 by right clicking and then selecting Send to – Compressed (zipped) folder but got this error:

xxx cannot be compressed because it includes characters that cannot be used in a compressed folder, such as ". You should rename this file or directory. 

The folder contains files with Swedish characters åäö in it. I cannot remember having any problems with this in Windows 7?

Calculator

The calculator (calc.exe) only accepts the period sign (.) as decimal delimiter. In Sweden we have comma (,) as decimal delimiter and this has always worked in all Windows programs for as long as I can remember. Of course any properly written Windows app would know to take such settings from Windows regional settings but apparently the decimal separator is hardcoded in the Windows 10 version of the calculator.
