问题
I use Python to connect to my postgresql data base like this:
conn=psycopg2.connect(database="fedour", user="fedpur", password="***", host="127.0.0.1", port="5432")
No problem for that.
But when I make a query and I want to print the cursor I have something like this:
"Fran\xc3\xa7ois" instead of "François" and it cause problem when I want to create a XML document with this. I thkink is come from my encodage, but I found any solution. I try to encode('utf-8') but doesn't work.
I have also seen something like this, but its only for mySQL
MySQLdb.connect(charset='utf8', init_command='SET NAMES UTF8')
Can you help me ? Thanks
回答1:
Make sure you're using the right encodind by running: print conn.encoding, and if you need, you can set the right encoding by conn.set_client_encoding('UNICODE'), or conn.set_client_encoding('UTF8').
回答2:
Does the value get inserted correctly when query is executed via command prompt?
If yes, then the problem is with your cursor execution.Try cur.execute(u"querystring");(The u indicates utf encoding)
If no, then you need to set the encoding type of postgres to consider utf-8. You can refer character encoding in Postgres to see how to set default character encoding for a database, and on-the-fly conversion from one encoding to another.
