Stabilized Technical Report

UTS #6, "A Standard Compression Scheme for Unicode" has been stabilized: There are no plans to ever publish another update for it. The last version can be found at https://www.unicode.org/reports/tr6/tr6-4.html.

SCSU defines a compact encoding, which is sometimes useful. However, Unicode text is much more commonly stored and transmitted in UTF-8 which is less compact (except for ASCII), much simpler, and does not present any security issues. For longer texts, general-purpose compression is effective and common. Therefore, there is no need to develop this report any further.
