Description

Following on from the fixes made under PROTON-576, some UTF-8 characters were getting incorrectly reported as invalid surrogates, when they were valid 3-byte encodings.

e.g.,
！！！
(╯°□°)╯︵ ┻━┻
etc.

This is an issue when streaming variable content such as Twitter messages which can often contain such characters.
