(Note to myself: code in C next time).
I tried ${var:} initially, it was giving me syntax errors (unless it was some other poorly coded shell expansions). In fact my first version looked much simpler. I thought « let me use a shell script, it will be an easy POC) » only to find out that UTF-8 multibytes were totally messing column alignments in string manipulations
and from then on I had to go deeper and messier into the script to the point that cheat sheets are required:
