The ✨on the last line takes up two characters in my terminal (iTerm) but '✨'.length evaluates to 1. Some options are to detect these characters or uses curses to more directly draw text at specific columns.

This whole thread seems somewhat relevant https://github.com/xtermjs/xterm.js/pull/2568

Another solution might be to interact more directly with the terminal, e.g. using blessed.
