| is not listed in the input set, why would it delete it? But several versions of tr do this, I guess this is "normal". It removes empty records, ruining column counts... and if I don't use -s, you get two consecutive newlines counting as multiple records, which ruins it the other way, adding extra records.
Trying to figure out a tr-alternative which isn't as stupid.

ldns-gen-zone
ldns-gen-zone(1) General Commands Manual ldns-gen-zone(1)NAME
ldns-gen-zone - read a zonefile and print it while adding DS records and extra RR's
SYNOPSIS
ldns-gen-zone ZONEFILE
DESCRIPTION
ldns-gen-zone reads a DNS zone file and prints it.
It is build for speed, not for a nice formatting. The output has one resource record per line and no pretty-printing makeup.
DNSSEC data (NSEC, NSEC3, RRSIG or DNSKEY) is not stripped. You may want to use ldns-read-zone for that. Existing DS records are also not
stripped.
The idea is to use this tool for quickly generating a representative artificial zonefile from a real zonefile, to use it for testing pur-
poses.
OPTIONS -a NUM Adds NUM extra artificial NS RRSets to the output. The RRSets owner names start with 'xn--' in an attempt to ensure uniqueness
(nl.-zone does not support IDN's - and this tool was written with that knowledge in mind).
An artificial NS RRSet has two NS records; ns1.example.com and ns2.example.com.
-p NUM Add NUM% of DS RRSets to the NS RRSets (anywhere between 1-4 DS records per RRSet).
-o ORIGIN
Sets an $ORIGIN, which can be handy if the one in the zonefile is set to '@' for example. If there is an $ORIGIN in the zonefile,
this option will silently be ignored.
-s This is the recommended way of processing large zones that are already sorted and canonicalized (ie lowercase). It skips the sorting
and canonicalization step that is required for properly grouping RRSets together (before adding any DS records to them. Skipping
this step will speed things up.
It is not recommended to use this option if you want to add DS records to unsorted, non-canonicalized zones.
-h Show usage and exit.
-v Show version and exit.
EXAMPLES
ldns-gen-zone -a 100000 -p 10 -s ./zonefile.txt
Read a zonefile, add 100.000 artificial NS RRSets and 10% of DS records, print it to standard output. Don't sort (will only work
well if the input zonefile is already sorted and canonicalized).
ldns-gen-zone -p 10 -s -o nl zonefile.txt | named-compilezone -s relative -i none -o zonefile_10.txt nl /dev/stdin
This creates a nicely formatted zone file with the help of named-compilezone. It adds 10% DS records to the .nl zone, reformats it
and saves it as zonefile_10.txt.

BUGS
Only undiscovered ones.
CAVEATS
May require a machine with a considerable amount of memory for large zone files.
Fake DS records hashes are generated as digest type SHA-256 (RFC4509). Be aware not to change the DIGESTTYPE #define in the source code in
anything else but 2 if you want to keep things realistic.
Despite a number of efforts, this program is still not the fastest in the world.
