Unicode to hex converter

This utility converts your input Unicode data into base-16 code points and then prints them one by one in the encoding you have chosen. Base-16 (also known as radix-16) is called the hexadecimal format, or simply the hex format. The hex format is made out of 16 symbols that consist of 0-9 and a-f (sometimes A-F). Before printing the hex code points, they are converted to one of nine encodings that we have added. They are – UTF8 that uses two to eight hex digits, then UTF-16-LE, UTF-16-BE, UCS-2-LE, and UCS-2-BE that use four or eight hex digits, then UTF-32-LE, UTF-32-BE, UCS-4-LE, and UCS-4-BE that use the maximum amount of storage, which is eight hex digits. For use in programming, you can add the prefix "0x" before hex values. For better output formatting, you can put a single space character between each hexadecimal value, as well as pad bytes that are an odd number hex characters in length with an additional zero to make all bytes an even length. For multibyte encodings, such as UTF-16, UCS-2, UTF-32, and UCS-4, you can also add the Byte Order Mark (BOM) endianness indicator. BOM for UTF-16-LE is 0xfffe, for UTF-16-BE it's 0xfeff, for UTF-32-LE it's 0xfffe0000, and for UTF-32-BE it's 0x0000feff.
