bytesToUnicode function
A function that returns a map of integers to Unicode strings.
Implementation
Map<int, String> bytesToUnicode() {
/// A function that returns a map of integers to Unicode strings.
/// It generates a mapping from byte values to Unicode characters, including printable ASCII characters, Spanish characters, and some special characters.
/// It first generates a list of byte values, creates a second list by copying the first one, and then appends any byte values that are not in the first list to both lists.
/// It then maps each byte value in the resulting list to its corresponding Unicode character and returns the resulting map.
