stdscr.getstr（）忽略键，只是字符串

Question

我只需要将输入的文本（字节）转换为字符串。但是，如果我在西里尔文按Backspace和某些字符，则python会向我抛出此错误：

UnicodeDecodeError: 'utf-8' codec can't decode byte 0xd0 in position 10: invalid continuation byte

我能做什么？

# -*- coding: utf-8 -*-
from re import sub
import curses


chatting = True
cols = 0
lines = 0


def get_msg(stdscr):
    str_text = ""
    while chatting:
        inpwin = curses.newwin(2, 30, 1, 0)
        text = inpwin.getstr()
        str_text = str(text, "utf-8") # this string throw error

        stdscr.addstr(0, 0, str_text)
        stdscr.refresh()


def main(stdscr):
    curses.echo()
    stdscr.scrollok(True)
    global cols
    global lines
    lines, cols = stdscr.getmaxyx()
    get_msg(stdscr)


curses.wrapper(main)
