最終效果

定義一個(gè)函數(shù)獲取圖形界面輸入的內(nèi)容并將輸入的中文轉(zhuǎn)為Unicode后顯示到圖形界面

    def to_unicode(self):
        # 獲取中文文本框內(nèi)容
        value_text=self.textEdit.toPlainText()
        print('輸入的中文內(nèi)容為:{}'.format(value_text))
        # 轉(zhuǎn)為Unicode
        unicode_text=value_text.encode("unicode_escape")
        print('輸入內(nèi)容的Unicode為:{}'.format(unicode_text))
        # 通過textBrowser進(jìn)行展示
        # self.textBrowser.setPlainText(str(unicode_text).replace("b", ""))
        self.textBrowser.setPlainText(str(unicode_text).strip("b'"))

self.pushButton.clicked.connect(self.to_unicode)# 設(shè)置按鈕的功能函數(shù)
