I was able to reproduce. Every attempt to paste חֶ֫סֶד into my User Notes resulted in a crash. I was able to type it in (without the accent).
EDIT: This happened with the latest version of Accordance (11.2.4) and Sierra. I've been having some weird graphical aberrations with Sierra (10.12), independent of Accordance.
