I think the general complaint here, by just about everyone, is
1. You make statements about Unicode without knowing anything about it.
2. You fail to acknowledge that Unicode is widely used and implemented,
and although some (or even many) things could have been designed
better, they work.
I bet that Unicode is the most widely used character set ever, except for US-ASCII and ISO 8859-1.

Of course - if compression is all you are looking at.
If you need an encoding for processing, where random access and fast and unambiguous decoding are
important, use one of the three encoding forms that the Unicode Standard defines.
If you need a byte serialization, use one of the encoding schemes associated with the above, or one
of the following ones, or invent your own
If you want a measure of compression combined with fast text streaming, use something like SCSU
(which is a sister standard to Unicode, not part of it directly) or BOCU-1 (which is defined in a
If you want maximum compression and don't need to be able to process directly and can afford slow
encoding and decoding, use zip/gzip/bzip2.
