Some Windows 10 modern UI apps (at least Mail and Calendar) have adopted the bad habit of MS office to replace simple quotes with "pretty" quotes during input.
In office you can disable it in the options, but I looked through all Windows 10 settings (and the old control panel as well), but I can't find it.
Is there any way to disable this behaviour? I have the feeling that this behaviour only affects multiline text boxes in modern UI apps.
Note: It is quite possible that this behaviour is specific to the german input language.
Ctrl + Shift + ' (apostrophe) Activate smart quotes
and do it again to turn off. This is standard behaviour of Windows' RichEdit control (used by wordpad compared to notepad's edit control).
