"ー" is http://en.glyphwiki.org/wiki/u30fc
I found this problem on f93fbad8f8, Windows 10 + PowerShell
It did not occur on bc39bf8d24

package main

import "github.com/rivo/tview"

func main() {
	text := tview.NewTextView()
	text.SetText("aaaー") // -> Displays nothing. Cannot halt application by Ctrl+C
	//text.SetText("ー") // -> Displays nothing too. But can halt application by Ctrl+C
	//text.SetText("ーaaa") // -> Displays "aaa"
	application := tview.NewApplication()
	application.SetRoot(text, true)
	application.Run()
}

I guess I chose the wrong unicode categories to find combining characters. Anyway, the last commit should fix this.
