... I will be honest. That statement confuses me.
At a glance, the output is what I'd expect.
Consulting the UTF8 table to the side (https://www.utf8-chartable.de/) and a
quick decimal to hex calculator
decimal | hex | symbol
43 | 2b | +
35 | 23 | #

I am honestly very uncertain how you'd get nim to comprehend a given number as
an octal.
