Hello,

Welcome to Microsoft Q&A,

While typing "6" in french keyboard it enters like "-6" in UWP Platforms

Derive from official document, it's by-design within UWP input control for no-us keyboard layout. if you want to input number, you could switch to US-keyboard or press Shift + Number. And you could also use the following code the detect which key pressed then convert it to the char.

private static char? ToChar(VirtualKey key, bool shift)  
{  
     
    if (32 == (int)key)  
        return ' ';  
  
    VirtualKey search;  
  
   
    foreach (var letter in "ABCDEFGHIJKLMNOPQRSTUVWXYZ")  
    {  
        if (Enum.TryParse<VirtualKey>(letter.ToString(), out search) && search.Equals(key))  
            return (shift) ? letter : letter.ToString().ToLower()[0];  
    }  
  
   
    foreach (var number in "1234567890")  
    {  
        if (Enum.TryParse<VirtualKey>("Number" + number.ToString(), out search) && search.Equals(key))  
            return number;  
    }  
  
    
    return null;  
}  

Usage

private void MyTextBox_KeyDown(object sender, KeyRoutedEventArgs e)  
{  
    var c = ToChar(e.Key, false);  
}
