Character return ??? instead kanji (32 bit work - 3.0.3, 64 bit not - 3.0.6) #324

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
Hello,

I'm trying access a SQL Server 2000 that have a Japanese database 
(Unfortunately I have no choice), and before (old machine in 32 bit) was 
running without problem, but when I try to install in a 64 bit with the same 
configuration I have the "???" response in the field.
Checking both machines with isql and tsql select the query, both returned the 
field with character correct.

What steps will reproduce the problem?
#!/usr/bin/python
import pyodbc

server=''
port=1433
user = ''
password = ''
database = ''
driver = 'FreeTDS'

con_string = r'DRIVER={%s};SERVER=%s;PORT=%s;UID=%s;PWD=%s;DATABASE=%s;' % 
(driver, server, port, user, password, database)
cnxn = pyodbc.connect(con_string)
cursor = cnxn.cursor()
cursor.execute("""SELECT TOP 1 field FROM T_table""")
row = cursor.fetchone()
print row[0]
print row[0].decode('sjis')

What is the expected output? What do you see instead?
Expected an string with kanji and return ???

What version of the product are you using? On what operating system?
Database [ MS Server Enterpise Edition ] in Windows NT
- Version: 8.00.2040
- Language: Japanese
- Server Collation: Japanese_CI_AS

Field - Varchar(1000) - Collation: Japanese_CI_AS
