问题
I'm sending an email address to my python webapp by sms using Twilio. However, when I attempt to convert the sms body containing the email address I get an exception.
<type 'exceptions.UnicodeEncodeError'>, UnicodeEncodeError('ascii', u'myemail\xa1gmail.com', 13, 14, 'ordinal not in range(128)'), <traceback object at 0x10cca5f8>)
Traceback (most recent call last):
File "/base/python27_runtime/python27_lib/versions/third_party/webapp2-2.5.1/webapp2.py", line 570, in dispatch
return method(*args, **kwargs)

from_body = str(cgi.escape(self.request.get('Body', None))).strip()
UnicodeEncodeError: 'ascii' codec can't encode character u'\xa1' in position 13: ordinal not in range(128)
I get that this is an encoding error that's stumbling on the @ character in the email address. And after googling this issue I found a recommendation of
sys.setdefaultencoding( "latin-1" )
But that simply replaced the @ with a � symbol.... What is the simplest way to overcome this?
回答1:
I contacted Twilio to get to the bottom of this and it turns out it's not a python problem. When a user sends in their email address (by sms) it sends in an ¡ character (instead of @) which is unfortunately non-ascii - hence the exception.
From Twilio:
Some carriers have not made the fix to allow the proper formatting to be preserved in SMS messages sent over their networks, so you will see corruption of @ signs in SMS handled by some carriers.
One potential fix is to enable unicode character encoding on your Twilio account. A potential downside to this is that you would be limited to sending SMS messages that are 70 characters or less in length
