For many years, most of the Internet ran on ASCII, a character set that had a limited number of accents and diacriticals, and which didn't support non-Roman script at all. Unicode, a massive, sprawling replacement, has room for all sorts of characters and alphabets, and can be extended with "private use areas" that include support for Klingon.
But for all that, I never dreamt that Unicode was so vast as to contain a special character for a "pile of poo."
