Incorrect `alpn` processing
I'm implementing alpn
's double escaping in my own zone parser and decided to check what BIND and Knot do. I noticed some strange behavior using kzonecheck
(version 3.3.4).
foo SVCB 1 . alpn=foo\\\092,bar
is incorrectly printed as:
foo SVCB 1 . alpn=foo\\,bar
foo SVCB 1 . alpn="foo\\092,bar"
is incorrectly printed as:
foo SVCB 1 . alpn="foo\\\\,bar
