Can the behavior be replicated with /bin/sh?
Worth a try.
Indeed. If the same bug exists in both shells Rocket is likely
to fix it sooner than IBM.
The fact that it's using pipe operators implies the shell is in play.
I *believe* pipe is a kernel facility which shell invokes with C RTL
calls (pipe(); fork(); exec(); dup2; ... ). Shell doesn't actually move
the data. But there's plenty wiggle room in the options shell
supplies to those C RTL calls: it might be able to enable/disable
autoconversion or tag the descriptors with CCSIDs (incorrectly?)
I just looked at the z/OS bash ported tools source code. My advice is to
ask the question on Rockets forum.
An IBM expert averred long ago on MVS-OE that the actual
conversion is performed by kernel.
As I said, I would take this to Rockets forum which is a more appropriate
place to discuss bash.
But does bash supply unsolicited arguments to utilities?
Appendix L describes too many knobs and levers.

I had to add the -B to prevent “head” from doing autoconvert on the file.
