如何在python的splinter中編碼字符？

Question

我使用splinter對網站進行功能測試。 只要我不輸入特殊字符（如德國Umlaute），測試就可以順利進行。

如何調整腳本以測試具有這些字符的條目？

這是我到目前為止嘗試過的：

# coding=utf-8

from splinter import Browser


URL = "http://www.example.com"
USER = raw_input("Username, please: ") # f.e. "Günther"

with Browser('') as browser:
    # Log in as administrator
    browser.visit(URL)
browser.fill('user', USER)

這是我得到的錯誤日志：

Traceback (most recent call last):
  File "test.py", line 47, in <module>
    browser.fill('user', USER)
  File "C:\Python27\lib\site-packages\splinter\driver\webdriver\__init__.py", line 230, in fill

    chunks = self.iterencode(o, _one_shot=True)

    return _iterencode(o, 0)

Answer 1

將USER指定為unicode對象：

USER = u"Günther"
       ^

如果字符串來自外部源，請對其進行解碼：

USER = USER.decode('<ENCODING-OF-THE-STRING>')

Answer 2

Unidecode是我遇到的最簡單的unicode處理程序。
