PROTON-576: updates to bring things into line with the patch on the JIRA, 
rather than a stale older version I actually applied (not having a good day :P)

> It seems like Proton-J has its own custom UTF-8 encoder, but relies on Java 
> String's built-in UTF-8 decoder. However, the code doesn't seem quite right 
> and complex double byte UTF-8 like emoji ('📔🚢🍛🍴🍹🏊🏄') can quite easily fail to 
> parse:
> |   |   Cause:1       :-  java.lang.IllegalArgumentException: Cannot parse 
> String
> |   |   Message:1     :-  Cannot parse String
> |   |   StackTrace:1  :-  java.lang.IllegalArgumentException: Cannot parse
