That was my point as well, and that is why I am wiling to do some setup
in ini-luatex.

The fact that BOMs are allowed in Unicode text files just means that
not all Unicode text files are valid shell scripts. That is in itself
not surprising: there are many other kinds of text files that are not
valid shell scrips either.

And even though my own files do not have a BOM, it certainly has a use:
many text editors (also on linux) do incorrect auto-guessing of the text
encoding without it. I work around that by disabling the automatic 
encoding. Instead I force my text editor to treat all text files as
UTF-8, but for many people that is not a feasible option.

Best wishes,
