I often use escape codes in meta title and meta description, and they render correctly in Google SERPS ... but ...
Can you use them (like an &mdash
; for example) in schema.org microdata values? I want these characters to be passed and render correctly in G+ snippets, as discussed here:

... what about utf-8 ?? thanks.
It's certainly legal according to the specs, and I would expect it to work fine.
