Dear Support Team,

we have recently been experiencing frequent issues with incorrect input from USB or Bluetooth keyboards or scanners. For some characters, incorrect key codes are recognized your browser, resulting in invalid input. From what we have observed, this occurs when entering key combinations (Shift + any key). For example, “_” becomes “-”, “/” becomes ‘7’, and “!” becomes “1”. If we scan the value into a native input field (WPF) or in Chrome/ Edge, the input is correct. Only in your browser is the input recognized incorrectly. We analyzed this using the following Fiddle and noticed that your browser recognizes different key codes than Chrome, Edge, etc.

Test JS Fiddle

Are you already aware of this issue? Is there a fix for this?

Thanks in advance!

Best regards!

Hi,

Can you try to set this property to true and see if the problem still occurs?
