To make things portable look up termcap(5) and tput(1) to ask the termcap database for the right control sequence for your terminal, and use those.

Interestingly apt don't do this, they hardcode sequences as I did.

Maybe they bet those sequences are the same on all terminals since 1970, espacially those marked "DEC Private" and it won't change soon?

I honestly don't know.

Most terminal emulations follow the ANSI terminal https://en.m.wikipedia.org/wiki/ANSI_escape_code , so these hard coded escape sequences simply happen to work on most virtual terminals, including windows console (running CMD) and windows terminal.
