Wonder if the OP has standard_conforming_strings='off' and
escape_string_warning='off'?

Both are set to ‘on’ for me for all versions (I believe those are default settings). I have 12devel indeed on my test system alongside 9.6, but I’ve tried it as well on PostgreSQL 10 running on a different distro with different locale settings and it produced the same result (check being true). 

I think Tom’s answer solves it, although I am wondering how did you get true in the statement quoted above on PostgreSQL 9.6, perhaps that result is actually from PostgreSQL 10?

Cheers,
