What were you trying to do that didn't work?

Attempting to use col -b to parse cat output on file with unicode SOH symbol at end of line EDIT: (and no new-line or line-feed character present either) produces no output with RHEL 8 util-linux versions. 

Please provide the package NVR for which bug is seen:

All util-linux package versions available from standard repository including the latest in beta.  

This does not occur on RHEL7, RHEL 9, and upstream versions of util-linux

How reproducible:

Execute cat command piping to col -b 

Example: # col -b < /<filename>

Steps to reproduce

1.  Using the file attached, execute the below command on RHEL 8 system.

     # col -b < /tmp/test.dat

• • you can also recreate this operation by having a file with only 1 line of text, and no line feed at the end.
    EXAMPLE hexdump output of test file
    ]# hexdump /tmp/test2.dat
    0000000 3532
    0000002

Expected results

The output show display as shown below: 

=======
RHEL 7:
=======
[root@R7]# cat J_B002_BOND_LOAD_DATE-test.dat | col -b
20210415

[root@R7]# rpm -qa util-linux
util-linux-2.23.2-65.el7_9.1.x86_64

=======
RHEL 9:
=======
[root@R9][root@R9]# cat J_B002_BOND_LOAD_DATE-test.dat | col -b
20210415

[root@R9]# rpm -qa util-linux
util-linux-2.37.4-11.el9_2.x86_64
 

Actual results

[root@R8]# cat J_B002_BOND_LOAD_DATE-test.dat | col -b
