MySQLdb can't initialize character set utf-8 error

问题

I am trying to insert some Arabic word into the arabic_word column of my hanswehr2 database Maria DB using the MySQLdb driver.

I was getting a latin-1 encode error. But after reading around, I found out that the MySQLdb driver was defaulted to latin-1 and I had to explicitly set utf-8 as my charset of choice at the mariadb.connect() function. Sauce.

The entire database is set to utf-8.

Code:

def insert_into_db(arabic_word, definition):
    try:
        conn = mariadb.connect('localhost', 'root', 'xyz1234passwd', 'hans_wehr', charset='utf-8', use_unicode=True)
        conn.autocommit(True)
        cur = conn.cursor()
        cur.execute("INSERT INTO hanswehr2 (arabic_word , definition) VALUES (%s,%s)", (arabic_word, definition,))
    except mariadb.Error, e:
        print e
        sys.exit(1)

However now I get the following error:

/usr/bin/python2.7 /home/heisenberg/hans_wehr/main.py
Total lines 87672
(2019, "Can't initialize character set utf-8 (path: /usr/share/mysql/charsets/)")

Process finished with exit code 1

I have specified the Python MySQL driver to use the utf-8 character however it seems to ignore this.

Any inputs would be highly appreciated.

回答1:

The charset alias for UTF-8 in MySQL is utf8 (no hyphen).

See https://dev.mysql.com/doc/refman/5.5/en/charset-charsets.html for available charsets.

Note, if you need to use non-BMP Unicode points, such as emojis, use utf8mb4 for the connection charset and the varchar type.

There is a thing called collations that helps encode/decode characters for specific languages. https://softwareengineering.stackexchange.com/questions/95048/what-is-the-difference-between-collation-and-character-set

I think u need to specify it when creating your database table or in the connection string. refer this: store arabic in SQL database
