A Standard Compression Scheme for Unicode implementation in Go
Description
This in an implementation of SCSU as described in
https://www.unicode.org/reports/tr6/tr6-4.html
Although UTF-8 is now the most commonly used and recommended encoding, in some
cases the use of SCSU can be beneficial. For example when storing or
transmitting short alphabetical texts (Arabic, Hebrew, Russian, etc.) where
general-purpose compression algorithms are inefficient, but SCSU provides nearly
50% compression ratio over UTF-8.
