Bit Complement Operator ~ And vec()
-The bit complement operator C<~> may produce surprising results if
-used on strings containing Unicode characters. The results are
-consistent with the internal encoding of the characters, but not with
-much else. So don't do that. Similarly for vec(): you will be
-operating on the internally encoded bit patterns of the Unicode
-characters, not on the code point values, which is very probably not
-what you want.
