Re: Bug or not about ASCII and Multi-Byte character set

As I have said a number of times now, DO NOT USE ASCII FOR NON-ASCII DATA!!!

Whilst some apps like pgAdmin may do what you expect, other apps and interfaces may not.

Instead of ASCII, use the correct encoding for your data, or try Unicode if unsure.

Multibyte characters are written correctly but readed wrong by the ODBC
driver. Seems to work on WinXP clients right. Only Win2k clients may
have this problem. This bug may be corrected in PostgreSQL 8.1.

After inserting several multi-byte characters with pgAdmin3(version: 1.2.1), i found the odbc driver can't provide the right data (application is written in visual c++ and call ODBC API to access db server). All displayed multi-byte char set data were not correct but the ASCII data was right. However, pgAdmin3 can correctly insert and select all data .
