Interesting. Pydev must be doing something behind the scenes because when i changed open() to io.open() i get error inside of eclipse now:

f.write(card+"\n")
  File "C:\python27\lib\encodings\cp1252.py", line 19, in encode
    return codecs.charmap_encode(input,self.errors,encoding_table)[0]
UnicodeEncodeError: 'charmap' codec can't encode character u'\u53c8' in position 32: character maps to <undefined>

....

io.open(filepath, "a", encoding="UTF-8") as f: 

Then it works in eclipse. But I seem to be having an encoding problem all over the place that works in eclipse but dosnt work outside of eclipse pydev.

Here is the flow of my data, im terrible at using unicode/encode/decode so could use some help here:

kanji_anki_gui.py:

def on_addButton_clicked(self):
    #code
    # self.kanji.text() comes from a kanji letter written into a pyqt4 QLineEdit
    kanji = unicode(self.kanji.text())
    card = kanji_anki.scrapeKanji(kanji,tags)
    #more code

kanji_anki.py:

def scrapeKanji(kanji, tags="", onlymeaning=False):
    baseurl = unicode("http://www.romajidesu.com/kanji/")
    url = unicode(baseurl+kanji)
    #test to write out url to disk, works outside of eclipse now
    savefile([url])
    
    #getting webpage works fine in eclipse, prints "Oh no..." in terminal
    try:
        page = urllib2.urlopen(url)
    except:
        print "OH no website dont work"
	return None

    #Code that does some scraping and returns a string containing kanji letters
    return card

def savefile(cardlist,filepath="D:/iknow_kanji.txt"):
    with io.open(filepath, "a") as f:
        for card in cardlist:
            f.write(card+"\n")
    return True
