Without knowing what hidden character(s) in those files, how one can guess what happened.

hexdump -C file_{1,2} can show what is the real difference, which may help to understand what is going on with awk print.

$ awk '{ print $0 " abc " }' file_{1,2}  
 abc ://github.com/
 abc ://github.com/
https://github.com/ abc 
https://github.com/ abc

Thanks. I found the answer already, but this would also have lead me in the

It shows a difference (single trailing dot verses double-dot) for the two files:

$ hexdump -C file_{1,2}
