#Frames

#Text windows
text1 = Text(insideFrame)
text1.config(font=("consolas", 12), undo=True, wrap='word')
text1.pack(side = LEFT, fill = BOTH, expand = 1)

text2 = Text(insideFrame)
text2.config(font=("consolas", 12), undo=True, wrap='word')
text2.pack(side = LEFT, fill = BOTH, expand = 1)

scrollbar = Scrollbar(text1)
scrollbar.pack(side=RIGHT, fill=Y)
scrollbar.config(command=text1.yview)
text1.config(yscrollcommand=scrollbar.set)

scrollbar = Scrollbar(text2)
scrollbar.pack(side=RIGHT, fill=Y)
scrollbar.config(command=text2.yview)
text2.config(yscrollcommand=scrollbar.set)

app.mainloop()

It gives the following error: messagetext2save=str(text2.get(0.0,END)) UnicodeEncodeError: 'ascii' codec can't encode character u'\xe1' in position 2: ordinal not in range(128)

任何人都可以帮我修复此代码。我在这里要做的是，当我在我的应用程序中输入英文文本时，它会将其翻译成另一种语言，当我将输出保存到＆＃34; .txt＆＃34;包含超出ASCII字符范围的unicodes的文件，它会出错，所以任何人都可以帮我修复上面的代码。我需要的是能够将文本内容保存到＆＃34; .txt文件中＃34;。
