console.log(stringUtils.fromUnicode('\\u0068\\u0065\\u006c\\u006c\\u006f')); // hello

// Test Encoding and Decoding
console.log(stringUtils.encodeBase64('hello')); // aGVsbG8=
console.log(stringUtils.decodeBase64('aGVsbG8=')); // hello

// Test Regex Utilities
console.log(stringUtils.extractEmails('Contact us at support@example.com.')); // [ 'support@example.com' ]
console.log(stringUtils.extractURLs('Visit https://example.com now!')); // [ 'https://example.com' ]

// Test Repetition and Captcha
console.log(stringUtils.repeatString('ha', 3)); // hahaha
console.log(stringUtils.generateCaptcha(8)); // Random 8-character captcha


console.log(stringUtils.sortCharacters('dcba')); // abcd
console.log(stringUtils.sortWords('banana apple cherry')); // apple banana cherry
console.log(stringUtils.uniqueCharacters('aabbcc')); // abc

// Test Partitioning
console.log(stringUtils.partition('hello world', ' ')); // ['hello', ' ', 'world']
console.log(stringUtils.rpartition('hello world hello', 'hello')); // ['hello world ', 'hello', '']

console.log(stringUtils.sliceString('hello', 1, 4)); // ell
console.log(stringUtils.getIndex('hello', 2)); // l
console.log(stringUtils.splitAt('hello', 2)); // [ 'he', 'llo' ]

// Test Multibyte Encoding
const bytes = stringUtils.encodeToBytes('hello');
console.log(bytes); // Uint8Array([...])
console.log(stringUtils.decodeFromBytes(bytes)); // hello

// Test Comparison Utilities
console.log(stringUtils.equalsIgnoreCase('Hello', 'hello')); // true
console.log(stringUtils.compareLexicographically('abc', 'abd')); // -1
console.log(stringUtils.startsWith('hello', 'he')); // true
console.log(stringUtils.endsWith('hello', 'lo')); // true
