Another issue in Japanese users is EUDC (End User Defined Character). Unfortunately for both postgres developers and application developers in Japan, many machine dependence characters are still used in popular mobile phones in Japan. Their native encoding is SHIFT_JIS, and we have an EUDC mapping for SHIFT_JIS to/from EUC_JP. But we don't have for UTF-8 to/from other encodings. That is one of the reasons why we cannot move to the UTF-8 world completely. Imagine that a module that manipulate EUDC text. It will be written in EUC_JP because SHIFT_JIS is not supported in postgres. Also, it cannot be rewritten in UTF-8 because there are no mapping for the characters used in it. -- Itagaki Takahiro -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
