copied!<p>If using Python 2.7 or later, use a dict comprehension to remap the dictionary to utf-8 before passing to DictWriter:</p> <pre><code># coding: utf-8 import csv D = {'name':u'马克','pinyin':u'mǎkè'} f = open('out.csv','wb') f.write(u'\ufeff'.encode('utf8')) # BOM (optional...Excel needs it to open UTF-8 file properly) w = csv.DictWriter(f,sorted(D.keys())) w.writeheader() w.writerow({k:v.encode('utf8') for k,v in D.items()}) f.close() </code></pre> <p>You can use this idea to update UnicodeWriter to DictUnicodeWriter:</p> <pre><code># coding: utf-8 import csv import cStringIO import codecs class DictUnicodeWriter(object): def __init__(self, f, fieldnames, dialect=csv.excel, encoding="utf-8", **kwds): # Redirect output to a queue self.queue = cStringIO.StringIO() self.writer = csv.DictWriter(self.queue, fieldnames, dialect=dialect, **kwds) self.stream = f self.encoder = codecs.getincrementalencoder(encoding)() def writerow(self, D): self.writer.writerow({k:v.encode("utf-8") for k,v in D.items()}) # Fetch UTF-8 output from the queue ... data = self.queue.getvalue() data = data.decode("utf-8") # ... and reencode it into the target encoding data = self.encoder.encode(data) # write to the target stream self.stream.write(data) # empty queue self.queue.truncate(0) def writerows(self, rows): for D in rows: self.writerow(D) def writeheader(self): self.writer.writeheader() D1 = {'name':u'马克','pinyin':u'Mǎkè'} D2 = {'name':u'美国','pinyin':u'Měiguó'} f = open('out.csv','wb') f.write(u'\ufeff'.encode('utf8')) # BOM (optional...Excel needs it to open UTF-8 file properly) w = DictUnicodeWriter(f,sorted(D.keys())) w.writeheader() w.writerows([D1,D2]) f.close() </code></pre>
