Get ASCII characters, html codes, hex codes, and decimal codes for different encodings via decimal code or hex code.

Install

You can install via npm or yarn.

npm

npm install --save ascii-lookup

yarn

yarn add ascii-lookup

Usage

Importing

You can import using ES6 imports. There are two methods: getASCIIItemForDecimal which will return ASCII info by a given decimal, and getASCIIItemForHex which will return ASCII info by a given hex code.

import { getASCIIItemForDecimal, getASCIIItemForHex } from 'ascii-lookup';

Arguments

getASCIIItemForDecimal accepts two arguments:

Parameter	Type	Optional	Description
dec	number	false	The ASCII decimal value
encoding	string (ASCIIEncoding enum in Typescript)	true	The type of encoding for the extended ASCII set - Default is UTF8

getASCIIItemForHex also accepts two arguments:

Parameter	Type	Optional	Description
hex	string	false	The ASCII hex value
encoding	string (ASCIIEncoding enum in Typescript)	true	The type of encoding for the extended ASCII set - Default is UTF8

Encodings

If you are using TypeScript you can import the ASCIIEncoding enum which will provide you with every supported encoding:

Example

import { getASCIIItemForDecimal, ASCIIEncoding } from 'ascii-lookup';

getASCIIItemForDecimal(128, ASCIIEncoding.CP437);

If you are using plain JavaScript the available encodings are:

utf-8	Unicode
big5	Chinese
ibm866	Russian
euc-jp	Japanese
euc-kr	Korean
gb18030	Chinese

Result

Both getASCIIItemForDecimal and getASCIIItemForHex return an object of type ASCIIItem:

Key	Type	Description
dec	number	Decimal code
hex	string	Hex code
html	string	HTML code
char	string	Character

A type for ASCIIItem is available for import in TypeScript:

import { getASCIIItemForDecimal, ASCIIEncoding, ASCIIItem } from 'ascii-lookup';

const result: ASCIIItem = getASCIIItemForDecimal(128, ASCIIEncoding.CP437);
