How can I create a fancier REPL prompt with styled strings? (was: Make `Base.textwidth` ignore ANSI sequences)

I was wondering if there was an easy workaround for this.

You could strip out the ANSI escapes (which are not part of Unicode) before calling textwidth, e.g. Strange characters in windows terminal - #4 by digital_carver

But probably better to use StyledStrings
