'ALLOW_BACKSLASH_ESCAPING_ANY_CHARACTER'
URL: https://github.com/apache/drill/pull/1663#issuecomment-604548389
@arina-ielchiieva, seems that the ticket for the "original" JSON Parser is
the one in the PR title: DRILL-7060. Or am I missing something (again)? Since
we've never done a back-port, no reason to add a ticket to request one. Did you
want a ticket for the EVF-based JSON parser?

> Some JSON files may have strings with backslashes - which are read as escape
> characters. By default only standard escape characters are allowed. So
