Key::Unicode on MacOS does not behave the same way as on Windows & Linux

[UE2020]

Describe the bug
On Windows & Linux, calling enigo.key(Key::Shift, Press) followed by enigo.key(Key::Unicode("1"), Press) produces an exclamation mark in a textarea. On MacOS, a number one is produced. This is reproducible only with numbers (shift + any letter produces the expected uppercase letter).

Expected behavior
Holding shift and a number should produce the special character associated with that combination regardless of the OS.

Environment

• OS: Tested on Windows 11, Arch Linux on X.org, and MacOS ventura 13.2.1 (22D68) running on Mac M2 Air
• Rust: rustc 1.79.0 (129f3b996 2024-06-10)
• Library Version: 0.2.1

If you want to enter text, you should always use the text() method. Entering individual keys is slower and -at least for now - can lead to inconsistent or unexpected behavior. I need to improve it

The text() method isn't a solution for me because I'm using enigo in a remote desktop app, where keys should be held for as long as the client on the other end holds them. Right now I think get_layoutdependent_keycode is at fault.

[UE2020]

@pentamassiv I fixed the issue in my project by replacing the get_layoutdependent_keycode function with a hardcoded match statement from this C function. Obviously this means that only ascii characters can be emulated with Key::Unicode, but that doesn't matter for my usecase. You can see the changes I made at my fork of enigo.

[UE2020]

Just curious: have you had any luck integrating my change into enigo? It should be easy to use that predefined keycode list, you can fallback to the old system when the provided char doesn't match any of the arms in my code.

Sorry, I had a look at the code but enigo is supposed to work for all languages and I'm not sure if this won't break it for other languages. I know enigo gets used a lot by many Asian speakers. I did not get the time to investigate this in depth.

I've been mostly fixing bugs and trying to finally get the tests in the CI to work to reduced the maintenance burden.
