No, it's easy, but not quite that easy.

Unicode code-points up to U+007F are represented as 8-bit bytes with the
same value, so counting bytes <0x80 gives you the number of US-ASCII
characters.  Characters above U+007F are represented with multiple bytes,
the first >= 0xC0, the trailing bytes are all >= 0x80.

So to count characters, one way is to count all bytes less <= 0x7F or >=
0xC0.
