AppVeyor 中的 UTF-8，Python 3.6

Question

1。摘要

我没有找到，如何将非 ascii 符号用于 AppVeyor 构建。

2。设置

我的简单 SashaAppVeyorEncoding.py 文件：

print('Саша наилучшая!')

我的简单 appveyor.yml 文件：

environment:

  matrix:

    - PYTHON: "C:\Python36-x64"
      PYTHON_VERSION: "3.6.3"
      PYTHON_ARCH: "64"
      PIP: "C:\Python36-x64\Scripts\pip"

platform: x64

build_script:

  - cmd: "%PYTHON%\python SashaAppVeyorEncoding.py"

我以 UTF-8 编码保存的两个文件。

3。预期行为

如果我运行 SashaAppVeyorEncoding.py 在我的终端或解释器中 SublimeREPL 文件，我得到：

D:\SashaPythonista>python SashaAppVeyorEncoding.py
Саша наилучшая!

如果我的 SashaAppVeyorEncoding.py 文件不包含西里尔符号：

print('Sasha superior!')

AppVeyor 构建 successful passed:

Build started
git clone -q --branch=master https://github.com/Kristinita/SashaPythonista.git C:\projects\sashapythonista-7l3yk
git checkout -qf 3a0393a5b9548a5debabebfc5e28d17f3000a768
%PYTHON%\python SashaAppVeyorEncoding.py
Sasha superior!
Discovering tests...OK
Build success

4。实际行为

My AppVeyor build failed:

Build started
git clone -q --branch=master https://github.com/Kristinita/SashaPythonista.git C:\projects\sashapythonista-7l3yk
git checkout -qf 262cef287d45b1548640b9a773b680de90b7d138
%PYTHON%\python SashaAppVeyorEncoding.py
Traceback (most recent call last):
  File "SashaAppVeyorEncoding.py", line 1, in <module>
    print('\u0421\u0430\u0448\u0430 \u043d\u0430\u0438\u043b\u0443\u0447\u0448\u0430\u044f!')
  File "C:\Python36-x64\lib\encodings\cp1252.py", line 19, in encode
    return codecs.charmap_encode(input,self.errors,encoding_table)[0]
UnicodeEncodeError: 'charmap' codec can't encode characters in position 0-3: character maps to <undefined>
Command exited with code 1

5。没有帮助

我在 SashaAppVeyorEncoding.py 文件的顶部添加 # -*- coding: utf-8 -*-，
I 命令到 appveyor.yml 文件，
我install win-unicode-console到appveyor.yml文件，

我更新的 SashaAppVeyorEncoding.py 文件：

# -*- coding: utf-8 -*-
print('Саша наилучшая!')

我更新的 appveyor.yml 文件：

environment:

  matrix:

    - PYTHON: "C:\Python36-x64"
      PYTHON_VERSION: "3.6.3"
      PYTHON_ARCH: "64"
      PIP: "C:\Python36-x64\Scripts\pip"

platform: x64

install:

  - cmd: "%PIP% install win-unicode-console"
  - cmd: chcp 65001

build_script:

  - cmd: "%PYTHON%\python SashaAppVeyorEncoding.py"

我的updated AppVeyor build:

Build started
git clone -q --branch=master https://github.com/Kristinita/SashaPythonista.git C:\projects\sashapythonista-7l3yk
git checkout -qf 11df07d4c424cd8e28a1b0db0f43906aa63f42f1

6。本地环境

操作系统和版本：
Windows 10 企业 LTSB 64 位 EN
Python:
3.6.3
chcp:
活动代码页：65001

Answer 1

看起来 python 没有打印到 AppVeyor 上的控制台——输出被重定向了。因此locale.getpreferredencoding() is used to encode Unicode text to bytes while printing to stdout. cp1252 supports only a few from a million of Unicode characters. To change sys.stdout.encoding here, you could set PYTHONIOENCODING=utf-8 envvar -- utf-8字符编码支持所有Unicode字符。
