Django WSGI Python编码(Django WSGI Python Encoding)

 我的Django Apache Wsgi设置有一个奇怪的问题。 我最近将我的网站移动到另一台服务器。 不幸的是，现在编码有些搞砸了。 当我运行这样的命令时： 
 
 barcode.generate_barcode("ean", "1341341234234") 
 
 生成的图像将在每个数字之间显示一些特殊字符，通常用于某些内切问题。 我猜它使用两个字节而不是一个来表示每个char或类似的东西。 
 
 
 如果我使用django ./manage.py runserver命令运行相同的设置。 生成的图像很好，没有添加特殊字符。 
 
 所以我得出结论，这必须是我的apache2 / mod_wsgi设置。 但版本与我的旧版本相同，即debian 6，apache2.2，mod_wsgi 3.3.2。 
 
 我想尝试更新版本的mod_wsgi，但编译失败。 
 
 有人能指出我正确的方向，这个编码错误可能有其原因吗？ 据我所知，WSGI上下文以某种方式使用错误的编码加载整个python脚本，否则我无法解释为什么硬编码字符串在图像上会出错。 
 
 在Apache conf.d / charset中： 
 
AddDefaultCharset UTF-8
 
 另外在我的vhost中： 
 
AddDefaultCharset UTF-8
 
 在apache2 / envvars中： 
 
export LANG='en_US.UTF-8'
export LC_ALL='en_US.UTF-8'
 
 Envvars用于apache运行级别脚本： 
 
if [ -z "$APACHE_ENVVARS" ] ; then
    APACHE_ENVVARS=$APACHE_CONFDIR/envvars
fi
 
 我还尝试在运行级别脚本中硬编码覆盖env变量。 
 
 在我的wsgi文件中： 
 
import sys
reload(sys)
sys.setdefaultencoding('utf-8')
 
 但似乎没有任何帮助。 我的图像仍然使用破碎的编码生成。 

I have a strange issue with my Django Apache Wsgi setup. I recently moved my site to a different server. Unfortunately now the encoding is somewhat messed up. When I run a command like this:
 
barcode.generate_barcode("ean", "1341341234234")
 
the resulting image will show some special character between every digit, typically for some endocing issue. I guess it is using two bytes instead of one to represent each char or something similar.
 
 
If I run the same setup with django ./manage.py runserver comand. The resulting image is fine, no special characters added.
 
So I came to the conclusion this must be something with my apache2/mod_wsgi setup. But the versions are identical to my old setup, i.e. debian 6, apache2.2, mod_wsgi 3.3.2.
 
I would like to try a newer version of mod_wsgi but compilation fails.
 
Can anyone point me in the right direction to where this encoding error might have its cause? To my understanding the WSGI context somehow loads the entire python script with a wrong encoding, otherwise I cannot explain why a hardcoded string would turn out wrong on an image.
 
In Apache conf.d/charset:
 
AddDefaultCharset UTF-8
 
In my vhost additionally:
 
AddDefaultCharset UTF-8
 
In apache2/envvars:
 
export LANG='en_US.UTF-8'
export LC_ALL='en_US.UTF-8'
 
Envvars is used in apache runlevel script:
 
if [ -z "$APACHE_ENVVARS" ] ; then
    APACHE_ENVVARS=$APACHE_CONFDIR/envvars
fi
 
I also tried to hardcode overwrite env vars in the runlevel script.
 
In my wsgi file:
 
import sys
reload(sys)
sys.setdefaultencoding('utf-8')
 
But nothing seems to help. My image is still generated with broken encoding.
