How to have something like head -c but working on colored characters
Clash Royale CLAN TAG#URR8PPP
Looks like head and sed treat color codes as actual characters. How can I get the first n actually visible characters from input?

Probably not very efficient, but with GNU awk, you could do something like:
gawk -v RS='33\[[;[:digit:]]0,16[[:alpha:]]|.' -v ORS= -v count=123 '
n += RT ~ /^[[:print:]]$/; n > count exit; print RT'
(where count is the number of characters you want to get).
Note that while head -c counts in number of bytes, the above counts in number of characters.
We're only considering control characters like newline, carriage return or tab, and escape sequences that are in the format: e[123;123x like the colour ones (where x is m) or cursor positioning ones (where x is H).

I'm looking for something very fast. Is there maybe a language in which I could easily write and compile this?
