如题，我本想用pyautogui写一个发微信的程序，但是发现只能发送英文的消息，该如何让write方法写入中文呢？

代码如下：

import pyautogui as pg
target = 'czh.png'
message = '你好'
wx = pg.locateCenterOnScreen('wechat.png', confidence = 0.85)
pg.moveTo(wx)
pg.click()

try:
    fullscreen = pg.locateCenterOnScreen('fullscreen.png', confidence = 0.85)
    pg.moveTo(fullscreen)
    pg.click()
except:
    print('already full screen')
searchbar = pg.locateCenterOnScreen('searchbar.png', confidence = 0.85)
start = (searchbar[0], searchbar[1] + 50)
pg.moveTo(start)
pg.click()


for i in range(100):
    try:
        zsq = pg.locateCenterOnScreen(target, confidence = 0.85)
        pg.moveTo(zsq)
        pg.click()
        pg.write(message)
        pg.hotkey('enter')
        break
    except:
        pg.hotkey('down')
