lenb

lenb

lenb returns the number of bytes used to represent the characters in a text string.

Different: string.prototype.length returns the number of characters in a text string.

lenb is the javascript version for lenb in Microsoft Excel.

Install

$ npm install lenb

Usage

const lenb = require('lenb')

lenb('foo')
// => 3

lenb('foobar')
// => 6

lenb('你好')
// => 4

lenb('こんにちは')
// => 10

NOTE: These functions may not be available in all languages.

NOTE: lenb counts 2 bytes per character only when a DBCS language is set as the default language. Otherwise lenb behaves the same as string.prototype.length, counting 1 byte per character.

The languages that support DBCS include Japanese, Chinese (Simplified), Chinese (Traditional), and Korean.
