I tried this now and converted all \\ to \. I still get the same problem

Ah - the plot thickens, and the light bulb goes on for me.  It's not
just a problem with read, but also with your use of 'echo' to try and
replay a just-read string.  'echo' and '\' don't mix.  You have to use
printf for any chance of portability.

printf %s\\n "\1"
printf %s\\n '\1'
I am surprised that dash doesn't take the opportunity to already extend "\1" or '\1' to char(1) in these cases. A mystery... :-)

I'll fix it. Thanks.
