[REQUEST] Handle other alphabets in input fields

[jbaublitz]

Is your feature request related to a problem? Please describe.
I was planning on using this for a terminal user interface for a flashcard app, but the text input doesn't seem to be able to display the Cyrillic or Arabic alphabet. I'm not sure if this is related to encoding or if there's a way to make the text inputs accept UTF-8, but currently those alphabets aren't displayed when you type them.

Describe the solution you'd like
I'd like difference alphabets to be able to be displayed when typed into a text box.

Is this feature present in other TUI products?
Yes.

Additional context
Arabic might be a little bit hard to handle only because it goes right to left and is cursive, but Cyrillic is usually pretty easy to implement with simply UTF-8 encoding.

Does your terminal handle them correctly? I don't see any reason they shouldn't already work, IIRC emoji (mostly) do and those should be more complicated.

[jbaublitz]

Yes, my terminal does handle them correctly. Specifically the behavior I'm seeing is that when I type Cyrillic into the text input box, nothing is displayed.

If you run ptg -g and enter a cyrillic character, what does it output?

This was the output.

PyTermGUI - Getch-practice/ ptg -g
