You are trying to store a Unicode codepoint \u201c
using an encoding ISO-8859-1 / Latin-1
that can't describe that codepoint. Either you might need to alter the database to use utf-8, and store the string data using an appropriate encoding, or you might want to sanitise your inputs prior to storing the content; i.e. using something like Sam Ruby's excellent i18n guide. That talks about the issues that windows-1252
can cause, and suggests how to process it, plus links to sample code!
SQLAlchemy users can simply specify their field as convert_unicode=True
.
Example:
sqlalchemy.String(1000, convert_unicode=True)
SQLAlchemy will simply accept unicode objects and return them back, handling the encoding itself.
Python: You will need to add # - * - coding: UTF-8 - * - (remove the spaces around * ) to the first line of the python file. and then add the following to the text to encode: .encode('ascii', 'xmlcharrefreplace'). This will replace all the unicode characters with it's ASCII equivalent.
Latin-1 (aka ISO 8859-1) is a single octet character encoding scheme, and you can't fit \u201c
(“
) into a byte.
Did you mean to use UTF-8 encoding?
I hope your database is at least UTF-8. Then you will need to run yourstring.encode('utf-8')
before you try putting it into the database.
The best solution is
do like this comment(add use_unicode=True
and charset="utf8"
)
db = MySQLdb.connect(host="localhost", user = "root", passwd = "", db = "testdb", use_unicode=True, charset="utf8") – KyungHoon Kim Mar 13 '14 at 17:04

Create a connection to the database. It is strongly recommended
that you only use keyword parameters. Consult the MySQL C API
documentation for more information.
host
string, host to connect
user
string, user to connect as
passwd
string, password to use
db
string, database to use
port
integer, TCP/IP port to connect to
unix_socket
string, location of unix_socket to use
conv
conversion dictionary, see MySQLdb.converters
connect_timeout
number of seconds to wait before the connection attempt
fails.
compress
if set, compression is enabled
named_pipe
if set, a named pipe is used to connect (Windows only)
init_command
command which is run once the connection is created
read_default_file
file from which default client values are read
read_default_group
configuration group to use from the default file
cursorclass
class object, used to create cursors (keyword only)
use_unicode
If True, text-like columns are returned as unicode objects
using the connection's character set. Otherwise, text-like
columns are returned as strings. columns are returned as
normal strings. Unicode objects will always be encoded to
the connection's character set regardless of this setting.
charset
If supplied, the connection character set will be changed
to this character set (MySQL-4.1 and newer). This implies
use_unicode=True.
sql_mode
If supplied, the session SQL mode will be changed to this
setting (MySQL-4.1 and newer). For more details and legal
values, see the MySQL documentation.
client_flag
integer, flags to use or 0
(see MySQL docs or constants/CLIENTS.py)
ssl
dictionary or mapping, contains SSL connection parameters;
see the MySQL documentation for more details
(mysql_ssl_set()). If this is set, and the client does not
support SSL, NotSupportedError will be raised.
local_infile
integer, non-zero enables LOAD LOCAL INFILE; zero disables
autocommit
If False (default), autocommit is disabled.
If True, autocommit is enabled.
If None, autocommit isn't set and server default is used.
There are a number of undocumented, non-standard methods. See the
documentation for the MySQL C API for some hints on what they do.

Use the below snippet to convert the text from Latin to English
import unicodedata
def strip_accents(text):
return "".join(char for char in
unicodedata.normalize('NFKD', text)
if unicodedata.category(char) != 'Mn')
strip_accents('áéíñóúü')
output:
'aeinouu'
I ran into this same issue when using the Python MySQLdb module. Since MySQL will let you store just about any binary data you want in a text field regardless of character set, I found my solution here:
Using UTF8 with Python MySQLdb
Edit: Quote from the above URL to satisfy the request in the first comment...
"UnicodeEncodeError:'latin-1' codec can't encode character ..."
This is because MySQLdb normally tries to encode everythin to latin-1. This can be fixed by executing the following commands right after you've etablished the connection:
db.set_character_set('utf8')
dbc.execute('SET NAMES utf8;')
dbc.execute('SET CHARACTER SET utf8;')
dbc.execute('SET character_set_connection=utf8;')
"db" is the result of
MySQLdb.connect()
, and "dbc" is the result ofdb.cursor()
.
