Ubuntu 17.10终端语言乱码问题求解（不修改系统主语言）

Got it, I’ve run into this exact issue before—having non-ASCII comments (like Korean) show up as gibberish in the terminal while keeping the system set to English. Here’s how to fix it step by step:

1. Verify and Adjust Terminal Encoding Settings #

First, make sure your terminal is using UTF-8 (the universal encoding that supports all languages, including Korean).

For Linux/macOS (bash/zsh) #

• Check your current terminal encoding:

  echo $LANG
  

  If the output isn’t en_US.UTF-8 (or another English UTF-8 variant), that’s likely the problem.
• Temporary fix (applies to current session only):

  export LANG=en_US.UTF-8
  

• Permanent fix (saves for future sessions):
  Open your shell config file (.bashrc for bash, .zshrc for zsh) with a text editor, add the line above, then reload the config:

  source ~/.bashrc  # or ~/.zshrc
  

For Windows Terminal/PowerShell #

• Open Terminal Settings (press Ctrl+,), select your profile (e.g., WSL Ubuntu, PowerShell).
• Under Appearance, set the font to a Korean-compatible one like Malgun Gothic or Noto Sans CJK KR.
• Under Advanced, set Character encoding to UTF-8.
• Save settings and restart the terminal.

2. Ensure Your Source File Uses UTF-8 Encoding #

Sometimes the issue isn’t the terminal—it’s the file itself using an old Korean-specific encoding like EUC-KR.

• Check the file’s encoding:

  file --mime-encoding your_code_file.ext
  

• If it’s not UTF-8, convert it:
  Use iconv for command-line conversion:

  iconv -f EUC-KR -t UTF-8 old_file.py > new_file.py
  

  Or use Vim to convert and save:
  1. Open the file in Vim: vim your_code_file.ext
  2. Set encoding to UTF-8: :set fileencoding=utf-8
  3. Save and exit: :wq

3. Use Terminal Tools That Support Multilingual Rendering #

Some basic tools might need extra flags to display non-ASCII characters correctly:

• When using less, add the -r flag to render special characters:

  less -r your_code_file.ext
  

• For Vim users, ensure Vim’s global encoding is set to UTF-8:
  Add this line to your ~/.vimrc (Linux/macOS) or %USERPROFILE%\_vimrc (Windows):

  set encoding=utf-8 fileencoding=utf-8
  

Quick Note #

If you’re still seeing gibberish, try switching to a modern terminal emulator like iTerm2 (macOS), GNOME Terminal (Linux), or Windows Terminal—these have better out-of-the-box support for multilingual characters than older terminals.
