Locale issue with typeins

[mkruselj]

Miętus on Discord reports that our typeins show him decimal numbers with dot as decimal separator, but this text entry doesn't work properly (it truncates the decimal part). They have to use comma instead, which works, but also means they manualyl have to replace the dot every time typein shows up. They are using Polish locale on Windows.

For me, Croatian locale on Windows, it's the other way around. Dot works just fine but comma is not parsed and truncates the decimal part to 0.
