Python3 UnicodeDecodeError [英] Python3 UnicodeDecodeError

问题描述

我有一个运行Python 3的服务器上运行的Django 1.8应用，在记录和打印带有特殊字符的字符串时出现UnicodeDecodeError。

I have a Django 1.8 app running on a server with Python 3 and I get a UnicodeDecodeError when logging and printing strings with special characters.

>：python --version
python 3.4.3

例如，如果我尝试在外壳程序：

For example, if I try to run a silly method in the shell:

def print_test():
       print('Test: èè') # any 'special char' like ä ç é û...

我得到堆栈跟踪：

>>> print_test()
Traceback (most recent call last):
  File "<console>", line 1, in <module>
  File "/home/sailingadmin/sailing-admin/utest.py", line 2, in print_test
    print('This is a test: \xe8\xe8')
UnicodeEncodeError: 'ascii' codec can't encode characters in position 16-17: ordinal not in range(128)

与 print（u'Test：èè'）

为什么会发生此错误？

utest.py是用utf-8编码的（源文件使用Python 3默认值）

utest.py is encoded in utf-8 (Python 3 default for source files)

>：echo $ LC_CTYPE
UTF-8

所有日志记录和打印都会引发UnicodeEncodeError ...

All logging and printing raises a UnicodeEncodeError...

推荐答案

LC_CTYPE格式如下： en_US.UTF-8 （点后的字符映射）
然后python将其用作日志记录和io的默认编码。

LC_CTYPE format as follows: en_US.UTF-8 (char map after the dot) Then python uses it as default encoding for logging and io.
