Support for multi-rune character input about tcell HOT 2 OPEN

Can you give an example? Is this combining characters or something like that?

from tcell.

Yes, this would be using combining characters. Given the following code that reads from stdin:

package main

import (
	"fmt"
	"os"

	"golang.org/x/term"
)

func main() {
	// switch stdin into 'raw' mode
	oldState, err := term.MakeRaw(int(os.Stdin.Fd()))
	if err != nil {
		fmt.Println(err)
		return
	}
	defer term.Restore(int(os.Stdin.Fd()), oldState)

	b := make([]byte, 16)
	var len int
	for {
		len, err = os.Stdin.Read(b)
		if err != nil {
			fmt.Println(err)
			return
		}
		if string(b[0:len]) == "q" {
			break
		}
		fmt.Println("read", len, "bytes")
		fmt.Printf("the char %s was hit\n", string(b[0:len]))
	}
}

I can run this and enter 🇾🇪 which consistently prints out the following:

read 8 bytes
the char 🇾🇪 was hit

I have tried using os.Stdin.Read with a tcell/tview project as a work-around, which works somewhat, but it seems to drop about every other typed character. This is without calling SetInputCapture on the tview application. Not sure if there is a way to fix that (I can ask on the tview site), but I thought it better to use EventKey if it could handle multi-rune character input.
