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.
