Nathan Lanza a0d52cbdc9 Add a check whether or not a str is utf8 prior to emplacing ...

Summary:
Highlighing junk data on VSCode can send a query for evaluate which
fails. In particular cases on Windows, this the error message can end
up as a c-string of [-35,-35,-35,-35,...]. Attempting to emplace this
as the error message causes an assert failure.

Prior to emplacing the error message, confirm that it is valid UTF8 to
eliminate errors such as mentione above.
