Question: switch case for strings not work

[nuintun]

export function stringEncode(value: string, encoding: string): ArrayBuffer {
  switch (encoding.toUpperCase()) {
    case 'UTF8':
    case 'UTF-8':
      return String.UTF8.encode(value);
    case 'UTF16':
    case 'UTF-16':
      return String.UTF16.encode(value);
    default:
      throw new TypeError('Unsupported encoding ' + encoding);
  }
}
