Pulls kaomoji from http://kaomoji.n-at.me/kaomoji.html into a text file that can be parse by the Google Japanese IME. Taken from https://gist.github.com/kakakaya/3b40a074a6dc7e8717154e85c0aa52e6 and added a few lines to make it work for me.

reload(sys)
sys.setdefaultencoding('utf8')

soup = BeautifulSoup(requests.get("http://kaomoji.n-at.me/kaomoji.html").text, "html.parser")
kaomojis = filter(None, ['かおもじ\t'+i.getText()+'\t顔文字' if '\n' not in i.getText() else None for i in soup.find_all('span', class_='kaomoji')])
with open('kaomoji_dic.txt', 'w') as f:
    f.write('\n'.join(kaomojis)+'\n')
