'ALLOW_BACKSLASH_ESCAPING_ANY_CHARACTER'
URL: https://github.com/apache/drill/pull/1663#issuecomment-604543765
@arina-ielchiieva, The ticket exists and this fix has been merged. (I'll
make sure it is in the new EVF-based version as well.)
@hossam-houssien, generally, fixes don't appear in already-released versions
of the product, only newer versions. It is quite easy to download Drill and do
your own build of the latest master so you can use the feature until Drill 1.18
is released.

> Some JSON files may have strings with backslashes - which are read as escape
> characters. By default only standard escape characters are allowed. So
> querying such files would fail. For example see:

> {code}
