我試圖使用ElementTree使用utf-8編碼的資料編寫一個xml檔案,如下所示：
#!/usr/bin/python
# -*- coding: utf-8 -*-
import xml.etree.ElementTree as ET
import codecs
testtag = ET.Element('unicodetag')
testtag.text = u'Töreboda' #The o is really ö (o with two dots over). No idea why SO dont display this
expfile = codecs.open('testunicode.xml',"w","utf-8-sig")
ET.ElementTree(testtag).write(expfile,encoding="UTF-8",xml_declaration=True)
expfile.close()
這樣會産生錯誤
Traceback (most recent call last):
File "unicodetest.py",line 10,in
ET.ElementTree(testtag).write(expfile,xml_declaration=True)
File "/usr/lib/python2.7/xml/etree/ElementTree.py",line 815,in write

UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 1: ordinal not in range(128)
使用“us-ascii”編碼代替工作正常,但不保留資料中的unicode字元.發生什麼事？
