    summary => 'Center text to a certain column width',
    description => <<'_',

This function can handle text containing wide characters and ANSI escape codes.

Note: to center to a certain character length instead of column width (note that
wide characters like Chinese can have width of more than 1 column in terminal),
you can turn of `mb` option even when your text contains wide characters.

Character should have column width of 1. The default is space (ASCII 32).
