You've confounded unicode with an encoding scheme (UTF-8). Some other encodings, say UCS-2, allow you to seek and read as in above example.

ASCII is a binary encoding, too. Being the simplest and a common default, there's rarely any problem with it.

Unicode is trouble, that's true. Its implementation almost invariably brings layers of abstraction, lasagna code, new levels of slow, new glitches, and sometimes, design changes that require extensive refactoring.

As an example, take the notion of double-width glyphs. Very useful, to be sure, but also quite disruptive. Fixed-width terminal is no more; cell addressing is no longer character addressing; text area layout re-flows as you edit it. Why stop there, in the limbo between character-cell and full GUI, why not assign a point width to every char?
