Invalid byte sequence for encoding & quot; UTF8 & quot;: 0xe99d2c, utf80xe99d2c

Invalid byte sequence for encoding "UTF8": 0xe99d2c, utf80xe99d2c


Query failed: ERROR: invalid byte sequence for encoding "UTF8": 0xe99d2c


The reason is that the client character set does not match the character set of the inserted content. PostgreSQL does not perform Character Set conversion by default. If the database is a UTF8 character set, the Chinese Character Set of the terminal is generally set to GBK (check the LANG environment variable for confirmation ), therefore, this encoding is stored in the database without conversion, and the database is UTF8. PostgreSQL reports the following error if it finds that it is not UTF8 encoding.
To enable the automatic character set conversion function, you must inform the PostgreSQL client of the character set used. At this time, you can set the PostgreSQL client encoding to GBK, and pg will automatically perform Character Set conversion.

The following is an experiment:

When writing code, you can specify the client character set encoding when creating a database link.
