At first the Unicode Consortium considered it to be a character encoding,<ref>https://unicode.org/reports/tr17/tr17-2.html</ref> but in 1999 changed its mind: although it was still considered a transfer encoding syntax, for a while it was no longer considered a character encoding because different compressors might yield different outputs for the same text.<ref>https://unicode.org/reports/tr17/tr17-3.html#Transfer Encoding Syntax</ref> However, in 2004 this decision was reverted and now SCSU is considered a ''compressing'' character encoding scheme, as opposed to a simple or compound character encoding scheme.<ref>https://unicode.org/L2/L2004/04288-tr17-5d2.html#CharacterEncodingScheme</ref>

Roman Czyborra (of [[GNU Unifont]]) wrote a decompressor.<ref>https://czyborra.com/scsu/scsu.c</ref> The reference compressorsdecompressor and decompressors areis found in [[International Components for Unicode]], along with a compressor written in Java.

[[Symbian OS]], an operating system for mobile phones and other mobile devices, uses SCSU to serialize strings.
