Usage / 使用方式

import { createBOMEncoding, detectBOMEncoding, EnumEncoding } from 'bom-encoding';

// Create BOM for UTF-8
const utf8BOM = createBOMEncoding(EnumEncoding.utf_8);
console.log(utf8BOM); // [0xEF, 0xBB, 0xBF]

// Detect BOM from buffer
const buffer = new Uint8Array([0xEF, 0xBB, 0xBF, 0x68, 0x65, 0x6C, 0x6C, 0x6F]);
const encoding = detectBOMEncoding(buffer);
console.log(encoding); // "UTF-8"

API

createBOMEncoding(encoding, options?)

Creates a BOM byte array for the specified encoding. 為指定的編碼創建 BOM 位元組陣列。

detectBOMEncoding(buffer, options?)

Detects the encoding from a buffer by checking its BOM. 透過檢查位元組順序標記從緩衝區偵測編碼。
