scrapy 中文乱码问题解决方案

http://www.ituring.com.cn/article/114408
最近在学习使用Python操作MySQL数据库，遇到了中文乱码问题。
一、MySQL数据库 库字符集参数:character set = utf8
表字符集参数:charset = utf8
列字符集参数:character set = utf8

二、Python文件 文件编码UTF-8
查看： :set fileencoding 改变： :set fileencoding=utf-8 文件头添加#-*- encoding:utf-8 -*-
创建MySQL数据库连接时加上编码参数，如下例:
conn = MySQLdb.Connection(host='localhost', user='root', passwd='123456', db='test',charset='utf8')
设置Python默认编码(非必须项)
reload(sys)
sys.setdefaultencoding('utf-8')

三、中文处理技巧(Unicode In Python, Completely Demystified) Decode early
Unicode everywhere
Encode late

四、更改mysql字符集： 查看 mysql> SHOW VARIABLES LIKE 'character%' +--------------------------+---------------------------------+
| Variable_name | Value |
+--------------------------+---------------------------------+
| character_set_client | utf8 |
| character_set_connection | utf8 |
| character_set_database | utf8 |
| character_set_filesystem | binary |
| character_set_results | utf8 |
| character_set_server | utf8 |
| character_set_system | utf8 |
| character_sets_dir | D:"mysql-5.0.37"share"charsets" |
+--------------------------+---------------------------------+
修改： To set the default to UTF-8, you want to add the following to my.cnf

[code][client]

[/code]

[code]default-character-set=utf8

[/code]

[code][mysql]

[/code]

[code] default-character-set=utf8

[/code]

[code][mysqld]

[/code]

[code] collation-server = utf8_unicode_ci

[/code]

[code]init-connect='SET NAMES utf8'

[/code]

[code]character-set-server = utf8

[/code]
