Using a three byte Emoji unicode character as a PasswordChar in a text box crashes the app.

[LaurentInSeattle]

On Windows 10 Avalonia 11.1.4

This crashes at runtime:
PasswordChar="🏍"

Exception thrown: 'System.FormatException' in System.Private.CoreLib.dll
An exception of type 'System.FormatException' occurred in System.Private.CoreLib.dll but was not handled in user code
String must be exactly one character long.

This works:
PasswordChar="⦿"

Not really an issue for me... And looks like a .Net for Windows bug...

'🏍' is not really a character, instead it's a pair of two characters, and could be more.

Since .NET doesn't allow setting such emoji as a char, we won't be able to support them. Unless we change API to use string instead. I.e. string PasswordMask or something.

> '🏍'
< (1,19): error CS1012: Too many characters in character literal

> "🏍".ToCharArray()
< char[2] { '\ud83c', '\udfcd' }

Yes, TIL, .Net does not fully support Unicode, is limited to UTF-16.
