- > Get the visual width of a string - the number of columns required to display it
 
- Some Unicode characters are [fullwidth](https://en.wikipedia.org/wiki/Halfwidth_and_fullwidth_forms) and use double the normal width. [ANSI escape codes](https://en.wikipedia.org/wiki/ANSI_escape_code) are stripped and doesn't affect the width.
 
- Useful to be able to measure the actual width of command-line output.
