Bug Description

Machine 1 with the Czech keyboard layout is connected to a Machine 2 with the German layout (which is probably not important).
The standard behavior of Czech keyboard layout:

pressing key corresponding to 3 on the English keyboard - writes š (s with hook)
pressing key corresponding to 3 on the English keyboard + Shift - writes 3

In RustDesk:

pressing the key corresponding to 3 on the English keyboard - writes š (s with a hook), correct
pressing the key corresponding to 3 on the English keyboard + Shift - writes Š (uppercase S with a hook)

So it looks like RustDesk detects if the input character is a letter and makes it uppercase when Shift is pressed. Numbers cannot be written.

This issue is the same for the other keys in that row, not only Š.

There is a related issue with the correct writing of uppercase Š in RustDesk. The Czech keyboard uses dead keys to write accents so the key two keys right from English 0, if pressed, writes a comma above the next entered character (like é) and with pressed with Shift, it adds a hook (like ě). In RustDesk, it always adds only a comma above the character, so it looks like Shift is ignored for the key.

I expect that the issue is general and not specific to the Czech keyboard layout.

How to Reproduce

On Windows for both machines, connect with Czech keyboard layout installed and set
press Shift + 3
writes Š

Expected Behavior

On Windows for both machines, connect with Czech keyboard layout installed and set
press Shift + 3
writes 3

Operating system(s) on local side and remote side

Windows 10 (both)

RustDesk Version(s) on local side and remote side

1.1.9 (both, installed version)
