Subject: 'tr' question passing tr delete chars argument coded in hex=20
into script as $varable

I am attaching 2 scripts renameLNX & renameLNX1
renameLNX=C2=A0 - delete characters hard-coded on tr - works OK
renameLNX1 - delete characters passed as $variable from cmdline argument=20
- does not work
 =C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0 - is this a=
 bug OR is something wrong with my coding ???

renameLNX1 dirxx '\x20\x21\x27\x28\x29\x2C'=C2=A0 #<-- passing hex delete=
=20
chars cmdline argument
fn2=3D$(echo $fn1 | tr -d $"$chars")=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=
=A0=C2=A0=C2=A0=C2=A0 #<-- does not work
See test results coded as #comments at end of attached renameLNX1 script

fn2=3D$(echo $fn1 | tr -d $'\x21\x24\x26\x27\x28\x29\x2A\x2C') #<--=20
hard-coded hex deletes OK
See script renameLNX OK

Is this a bug OR is something wrong with my coding ???
Thanks, Owen
