InvalidSelectorException when select element for Python Selenium with xpath

I have this html snippet:

<div class="btn">
    <a href="javascript:void(0)" class="S_btn_b" node-type="OK">
        <span>确定</span>
    </a>
</div>

And I want to select the 确定 element and click it. I tried the following selector with xpath:

confirm_btn = driver.find_element_by_xpath('//div[@class="btn"]//span[text()="确定"]')

But the program just complain that that is not a valid selector with this Exception:

Traceback (most recent call last):
  File "test.py", line 63, in <module>
    ac.move_to_element(driver.find_element_by_xpath('//div[@class="btn"]/span[text()="确定"'))
  File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/remote/webdriver.py", line 230, in find_element_by_xpath
    return self.find_element(by=By.XPATH, value=xpath)
  File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/remote/webdriver.py", line 662, in find_element
    {'using': by, 'value': value})['value']
  File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/remote/webdriver.py", line 173, in execute
    self.error_handler.check_response(response)
  File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/remote/errorhandler.py", line 166, in check_response
    raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.InvalidSelectorException

Did I do something wrong ?

If you do not mark your XPath expression as Unicode, the Hanzi will get mangled when the search command is sent to the browser and the search will search for something else than what you want so mark your XPath expression as Unicode:

confirm_btn = driver.find_element_by_xpath(u'//div[@class="btn"]//span[text()="确定"]')
