Following item in HISTORY: * Add support for 3 and 4-byte UTF8 characters (John Hansen) Previously only one and two-byte UTF8 characters were supported. This is particularly important for support for some Chinese characters.
is wrong since 3-byte UTF-8 characters are supported since UTF-8 support has been added to PostgreSQL. Correct description would be: * Add support for 4-byte UTF8 characters (John Hansen) Previously only up to three-byte UTF8 characters were supported. This is particularly important for support for some Chinese characters. In the mean time I wonder if we need to update UTF-8 <--> locale encoding maps. The author of the patches stated that "This is particularly important for support for some Chinese characters". I have no idea what encoding he is reffering to, but I wonder if the latest Chinense encoding standard GB18030 needs 4-byte UTF-8 mappings. If yes, we surely need to update utf8_to_gb18030.map. Anybody familiar with GB18030/UTF-8? -- SRA OSS, Inc.
