print '%s.%s ():%s '% (f.__module__, f.__name__, F ())
# returns the default character encoding
P (sys.getdefaultencoding) # used by the current system
returns the encoding p used to convert

In the Apache configuration file httpd.conf
1) in the configuration file, look for lines that contain "AddLanguage" or "Addcharset", and add one line to the front of the lines:
Adddefaultcharset GB2312
2) Develop good habits and add this line to
Generally, the system code in Windows is gb2312 (the Chinese version of Windows). Because I prefer UTF-8 encoding, I will share with you the modification method.
If you want to make the new build project, java files directly make the UTF-8, you
1. Modify the default code of JSP created by myeclipse:
Window-> Search JSP-> modify the value of encoding. You can select gb13080 or UTF-8..
2. Modify the default JSP editor of myeclipse:
Windows> preferences> General> editors> file
Turn the default environment into UTF-8 and look at the graph analysis:On the windows->preferences.So the whole environment becomes UTF-8, but it's not enough,Also, if you need all the files to be set to UTF-8, then:If you only need to set up a Java

1. Overview
This article mainly includes the following aspects: Coding basic Knowledge, Java, System software, URL, tool software and so on.
Java development, often encountered garbled problems, once encountered such a problem, often very ridiculous,
about the historical evolution of the code, UTF-8 is how to develop, why Windows still keep GBK encoding ...
And so on, online a search a lot of, most of them are forwarded, share after the same content, still can not solve my inner doubts ...
