Another encoding issue

[frdmn]

As mentioned in #1, there's still an issue with some surrogates:

<*sql> Could not save SAY to database caused by: <class 'UnicodeEncodeError'> 'utf-8' codec can't encode character '\udcf3' in position 15: surrogates not allowed

and

<*sql> Could not save SAY to database caused by: <class 'UnicodeEncodeError'> 'utf-8' codec can't encode character '\udcd0' in position 0: surrogates not allowed

[frdmn]

Some more:

<*sql> Could not save SAY to database caused by: <class 'UnicodeEncodeError'> 'utf-8' codec can't encode character '\udcb4' in position 3: surrogates not allowed
<*sql> Could not save SAY to database caused by: <class 'UnicodeEncodeError'> 'utf-8' codec can't encode character '\udcb4' in position 7: surrogates not allowed
<*sql> Could not save SAY to database caused by: <class 'UnicodeEncodeError'> 'utf-8' codec can't encode character '\udcfc' in position 164: surrogates not allowed

It says EncodeError and not DecodeError, so I guess it fails on this: message.encode('utf-8') @ line 112

Does that mean that the incoming message is something that can't be encoded to utf-8, maybe utf-16?

@buxxi Not sure if it's that elegant, but we could suppress those encoding issues for now:

message = message.encode('utf-8', 'ignore').decode('utf-8', 'replace')
