This package is a fork of wcwidth.

- Drop useless
defaultspackage wich introduce an indirect dependencies. - Cleanup npm tarball (only ship required files).
- Node.js v14 or higher

$ npm i @topcli/wcwidth
# or
$ yarn add @topcli/wcwidthimport wcwidth from "@topcli/wcwidth";
'한'.length // => 1
wcwidth('한'); // => 2
'한글'.length // => 2
wcwidth('한글'); // => 4wcwidth() and its string version, wcswidth() are defined by IEEE Std
1002.1-2001, a.k.a. POSIX.1-2001, and return the number of columns used
to represent the given wide character and string.
Markus's implementation assumes the wide character given to those functions to be encoded in ISO 10646, which is almost true for JavaScript's characters.
