None of the other explicitly listed encodings are unicode encodings, and the "other" category is tiny. So the statement is still true. Some browsers don't even support other unicode encodings, so this doesn't surprise me. UTF-16 is the only one that even stands a chance; I've never seen UTF-32 used for files, and I've never seen UTF-7 used at all. I suspect UTF-16 is more efficient than UTF-8 for east Asian scripts, but that advantage probably dwindles when content is gzipped.<p>It's good news that Google are now decomposing ligature codepoints, although I do wish they had a version of their search that was literal; especially with programming-related and other technical searches, the special characters it filters out are often crucial.
