I could've sworn I saw some instructions somehwere about this, but now I can't find anything and I'm starting to second-guess myself.

For records from the early 1600s (particularly these), if what is very clearly a U is used as a consonant instead of a V (e.g. "Dauidt" or "Siluester"), is that always keyed as a "u" or are there times when it should be keyed as a "v"?
