> Unicode is now used by everyone in China, having finally mostly migrated from GB encoding I doubt it. Actually Baidu and other major sites are still on GB2312/GB18030. There are practical reasons as most of the frequently used (3000+ characters) Chinese glyphs take two bytes in GB2312, but three in UTF-8. Many URIs contain escaped GB2312 instead of escaped UTF-8. For mobile(, not only 3G, but more significantly, the GPRS/EDGE/WAP) users, every bit counts.
