> The module wcwidth implements the same Markus Kuhn algorithm defined in
> POSIX.1-2008 to return the number of cells a unicode string is expected to
> occupy.
> The module wcwidth is used by hundreds of libraries including pytest and
> prompt-toolkit (used in ipython). It replaces 379 lines of bespoke code in
> cqlshlib.
> {quote}from wcwidth import wcswidth # at [https://pypi.org/project/wcwidth/]

> wcwidth appears to be used only by one line in formatting.py:
> return bval if colormap is NO_COLOR_MAP else color_text(bval, colormap,
> wcwidth.wcswidth(bval))
