Package description
The is-fullwidth-code-point npm package is used to determine if a given Unicode code point will be displayed as full-width in a terminal. Full-width characters take up two spaces in a monospace grid, as opposed to half-width characters that take up one space. This is particularly useful when dealing with CJK (Chinese, Japanese, and Korean) characters, emojis, or other symbols that may not conform to the standard width of ASCII characters.
Check if a code point is full-width
This feature allows you to check if a single Unicode code point is considered full-width. The function returns a boolean value.
const isFullwidthCodePoint = require('is-fullwidth-code-point');
console.log(isFullwidthCodePoint('あ'.codePointAt(0))); // true
console.log(isFullwidthCodePoint('A'.codePointAt(0))); // falseThis package calculates and returns the width of a string by considering full-width characters and ANSI escape codes. It uses is-fullwidth-code-point internally to determine the width of individual characters.
Based on the wcwidth implementation in C, this package provides a JavaScript function to get the printable width of a string on the terminal. It is similar to is-fullwidth-code-point but works at the string level rather than individual code points.
