Talk:Standard Compression Scheme for Unicode

"1 byte per character"
When it says 1 byte per character (plus overhead) for many text files, that's exactly what it means. As long as they don't use obscure control characters, all text files in ASCII or ISO-8859-{1,5-9,11} use 1 byte per character plus a couple bytes at the start to set the mode. Not ~1 byte, 1 byte.--Prosfilaes 06:22, 24 March 2006 (UTC)


 * You're right; I shouldn't have added the tilde. —Steve Summit (talk) 15:45, 24 March 2006 (UTC)


 * ISO-8859-1 you are correct about, but other common encodings like windows-125x and the other parts of ISO-8859 do not map to contiguous unicode code points. Plugwash 23:16, 29 July 2006 (UTC)


 * ISO-8859-{1,5-9,11} map to contiguous Unicode code points. I think that's many text files.--Prosfilaes 17:52, 30 July 2006 (UTC)


 * the upper half of ISO-8859-5 mostly maps to $400-$45F but there are a number of positions that don't, in partiticular positions A0,AD,F0 and FD Plugwash 18:12, 30 July 2006 (UTC)

Compression vs. Delta-Compression.
It is the compression that matters, that is the sum of Compression1+Compression2; not Compression2 alone, when using multiple compression algorithms. Comparing the compression gain of BOCU/SCSU and UTF-8/UTF-16 is unfair - because SCSU/BOCU stream is already compressed. . Please correct if wrong.
