Unicode is encoded using several competing encodings, of which UTF-8 is the
most used. In a Unicode encoding, multiple subsequent bytes can be used to
the world has standardized on UTF-8.
UTF-8 treats the first 128 codepoints, 0..127, the same as ASCII. They take
-only one byte per character. All other characters are encoded as two or more
-(up to six) bytes using a complex scheme. Fortunately, Perl handles this for

us, so we don't have to worry about this.
