// UTF-8 byte size using TextEncoder
function getUtf8ByteSize(str) {
  return new TextEncoder().encode(str).byteLength;
}

// UTF-16 byte size (JavaScript internal encoding)
function getUtf16ByteSize(str) {
  return str.length * 2; // Each code unit = 2 bytes
}

// Base64 encoded size from UTF-8

// Usage
const text = 'Hello, World! 안녕하세요 🌍';
console.log('Characters:', [...text].length);     // 19
console.log('UTF-8 bytes:', getUtf8ByteSize(text)); // 33
console.log('UTF-16 bytes:', getUtf16ByteSize(text)); // 40
console.log('Base64 size:', getBase64Size(text));   // 44
