Cutting any variable-width encoded string after a certain number of code units
is as useful as to cut a dollar bill in half. After you have done it, it loose
it's value.

Having said that, the same applies to cutting a string after a certain number of
code points, but here you could compare it to tear off a corner of a bill.

Counting graphemes or grapheme clusters is usually the way to go.
