UTF-8 encoding failure

UTF-8 encoding failure

Hi,

Is this the right place to report bugs?

The attached program creates a table with Japanese column names. When the column names are retrieved in a query using PQfname, and invalid string is returned. The invalid column names can also be seen in PGAdmin III. This only seems to happen with one (or more?) specific Japanese character.

Operating System: Windows Vista Ultimate SP2 32bit
PostgreSQL server versions: 8.4.2 and 8.3.3 both fail
libpq version: 8.3.6
Database encoding: UTF8
Client encoding:
- UTF8: does not return the same column name used to create the table.
- SJIS: "select * from table" fails with error:
    ERROR:  invalid byte sequence for encoding "UTF8": 0xe59eff
    HINT:  This error can also happen if the byte sequence does not match the encoding expected by the server, which is controlled by "client_encoding".

>From what I can see the character in question has the following encodings:
SJIS:     8c b4
UTF-16:     9f 53
UTF-8:     e5 8e 9f

Any chance this problem could be fixed soon?

Re: UTF-8 encoding failure

Hi,

This worked fine, as you can see in the attached result. However, I can see that my database has a different locale (English_United Kingdom.1252) from yours (C). Can this cause the problem?

Regards,

Martin
