The 5% performance loss you have mentioned may be explained
that way. But there are some more details, in particular
checking which encoding is used is only the first step,
the next step is finding the C function implementing the
relevant functionality. This is also currently not very
efficient (except for ASCII-based one-byte-per-character
encodings, where there are a lot of shortcuts). For some
more details, please see Section 4.4 of my paper on Ruby
internationalization at the 31st Internationalization and
Unicode Conference in October 2007.

It wouldn't bring much speed improvement.
It's a bit like asking why variables aren't typed in
Ruby.

>Why is creating a hierarchy of String subclasses, one for
>each encoding, a bad idea?

It's not necessarily a bad idea. But it wouldn't bring much
speed. And it would either lead to a totally different
implementation inside, or it would stay at virtually the
same speed.
