\032 is space. Go read STD13 aka RFC 1034 and RFC 1035.

\032 is not a space.

Decimal 32 (0x20, \040) is a space.
\032 is a Ctrl-Z (26 decimal, 0x1a)

Typo I’d say. DB-drive  DNS servers, which don’t keep their entries in traditional PTR-record text format, can fall 
victim to this. Rather than parse the text every times, they just spit out whatever is in the table column, even if 
it has embedded spaces. I’ve seen this happen in SnitchDNS.
