Notes:
Only mention this one because it was noted that doublebyte stuff is generally handled non-uniform across the system due to differing technologies being used. It was indicated, in some manner, that the older stuff was broken, but anything newly developed ought to work.  That doesn't appear to be the case here.

[1] if JIRA can't display the above doublebyte chars:
