checkEncoding

Detect character encoding of Uint8Array data.

API

checkEncoding

Return

Argument	Description	Type
`string`	Detected encoding type	`string`

Parameters

Parameter	Description	Type	Default
`uint8Array`	Data to detect	`Uint8Array`	Required

Example

Basic Usage

import { checkEncoding } from 'ranuts';

const data = new Uint8Array([0x48, 0x65, 0x6c, 0x6c, 0x6f]); // "Hello"
const encoding = checkEncoding(data);
console.log(encoding); // 'UTF-8' or other detected encoding

Detect File Encoding

import { checkEncoding } from 'ranuts';

async function detectFileEncoding(file) {
  const arrayBuffer = await file.arrayBuffer();
  const uint8Array = new Uint8Array(arrayBuffer);
  const encoding = checkEncoding(uint8Array);
  return encoding;
}

Text Decoding

import { checkEncoding } from 'ranuts';

function decodeText(uint8Array) {
  const encoding = checkEncoding(uint8Array);
  const decoder = new TextDecoder(encoding);
  return decoder.decode(uint8Array);
}

Notes

Dependency: Uses jschardet library for encoding detection.
Default encoding: If detection fails, defaults to 'utf-8'.
Accuracy: Encoding detection is not 100% accurate, especially for short text.
Use case: Commonly used for file processing, text decoding, character encoding conversion, etc.
