Encoding issues

Hi,

I recently implemented the bot example using django. However the fb send api returned an error of internal failure related to oauth.

{"error":{"message":"(#-1) Send API unexpected internal error","type":"OAuthException","code":-1,"error_subcode":2018012,"fbtrace_id":"BZ8p\/q9haBY"}}

The problem is related to the message object ,as you might read, text must be UTF-8 encoded and less than 640char.

All the library is beautifully written and respects UNICODE, however text must be encoded as follows:

page.send(sender_id,message.encode('utf-8'))

so that it can reliably echo back text messages.

If you agree I can make a pull request modifying Page.send(…) such that

text = message if isinstance(message, str) else None is changed for

text = message if isinstance(message, str) else message.encode('utf-8') if isinstance(message,unicode) else None

This will allow it to support unicode strings and respect facebook´s api.
