Using Korean input/output with Windows' console (cmd)

Environment: Windows 10 64-bit, English version.  Installed Korean IME.


Summary

If file names are in Korean (e.g. downloaded files), Windows can display the Korean file name in Explorer without any problem, but it will not display the file name properly.  And, you can't enter Korean in cmd.

[1] only displaying is needed
Go to this page, http://fightingmamoru.tistory.com/49
Download the font and install it, and then in cmd, change the font to "Bitstream Vera Sans Mono"

[2] both displaying and entering is needed
Go through above step [1], and install ConEmu (https://www.fosshub.com/ConEmu.html), change the font as in step [1].

Installing Python 2 and 3 together on Windows 10 with Eclipse Pydev

I already have Python 2.7 on Windows 10, and needed Python 3.x keeping 2.7.  This method works fine with Eclipse Pydev as well.  There are other ways to do have Python 2 and 3 together in Windows system, but I found this way is the simplest and easiest.

Environment:
Windows 10 64-bit. Python 2.7 64-bit, Eclipse+Pydev are already installed.

Steps:

1. Download Python 3.x 64-bit (Windows Installer) -- same for 32-bit.
   NOTE: as of today (2017/1/4), it's better to install Python 3.5 (https://www.python.org/downloads/release/python-352/), not the latest 3.6, since TensorFlow is now available for Windows but it only installs with python 3.5, not 3.6.
2. Install it with default setting.  Do not add it to PATH.
3. Run Eclipse
4. Go to Windows -> Preferences -> Pydev -> Interpreters -> Python Interpreters, then click on "Quick Auto-config"

How to use it:

• Python 3.6 for Windows installer installs it in:
  C:\Users\<USERNAME>\AppData\Local\Programs\Python\Python36\python.exe
  
  My Python 2.7 is installed in:
  C:\opt\Python27\python.exe
  
  Since the PATH is not added, if you type "python" in console, it's Python 2.7.
• To use Python 2 or 3:
• Python 2: py -2 <script name>
• Python 3: py -3 <script name>
• Python 2 PIP: py -2 -m pip install <module>
• Python 3 PIP: py -3 -m pip install <module>
• Eclipse-Pydev
1. New Pydev project
2. Set Grammar version
3. Set Interpreter
