how to set system locale to UTF-8 in command line

---

### 🤖 Cursor Assistant

I can help you set the system locale to UTF-8. Since you're on macOS with zsh, here are the methods:

## Temporary (Current Session Only)

```bash
export LANG=en_US.UTF-8
export LC_ALL=en_US.UTF-8
```

## Permanent (Add to Shell Profile)

Add these lines to your `~/.zshrc` file:

```bash
export LANG=en_US.UTF-8
export LC_ALL=en_US.UTF-8
```

Then reload your shell configuration:
```bash
source ~/.zshrc
```

## Verify Current Locale

Check your current locale settings:
```bash
locale
```

## View Available Locales

To see all available UTF-8 locales on your system:
```bash
locale -a | grep UTF-8
```

## Common UTF-8 Locale Options

- `en_US.UTF-8` - US English
- `en_GB.UTF-8` - British English
- `C.UTF-8` - Minimal locale (if available)

## Troubleshooting

If you encounter issues, you can set individual locale categories:
```bash
export LC_CTYPE=en_US.UTF-8
export LC_NUMERIC=en_US.UTF-8
export LC_TIME=en_US.UTF-8
export LC_COLLATE=en_US.UTF-8
export LC_MONETARY=en_US.UTF-8
export LC_MESSAGES=en_US.UTF-8
```

The most common approach is to just set `LANG` and optionally `LC_ALL` in your `~/.zshrc` file, which will apply UTF-8 encoding to all locale categories.

I see you're on a Linux system (appears to be a container or remote server) and the locale `en_US.UTF-8` isn't installed/generated. Here's how to fix it:

## Fix Locale on Linux

Run these commands:

```bash
# Install locales package (if not already installed)
apt-get update && apt-get install -y locales

# Generate the en_US.UTF-8 locale
locale-gen en_US.UTF-8

# Update locale configuration
update-locale LANG=en_US.UTF-8 LC_ALL=en_US.UTF-8

# Set for current session
export LANG=en_US.UTF-8
export LC_ALL=en_US.UTF-8
```

## Make it Permanent

Add to your `~/.bashrc` or `~/.bash_profile`:

```bash
export LANG=en_US.UTF-8
export LC_ALL=en_US.UTF-8
```

Then reload:
```bash
source ~/.bashrc
```

## Alternative: Use C.UTF-8 (Minimal, Always Available)

If you just need UTF-8 support without full localization:

```bash
export LANG=C.UTF-8
export LC_ALL=C.UTF-8
```

This is often simpler for containers/servers where you don't need full locale support.

## For Docker Containers

If this is a Docker container, add to your Dockerfile:

```dockerfile
RUN apt-get update && apt-get install -y locales && \
    locale-gen en_US.UTF-8 && \
    update-locale LANG=en_US.UTF-8 LC_ALL=en_US.UTF-8

ENV LANG=en_US.UTF-8
ENV LC_ALL=en_US.UTF-8
```

The quickest fix for your immediate issue is to run:
```bash
locale-gen en_US.UTF-8 && export LANG=en_US.UTF-8 && export LC_ALL=en_US.UTF-8
```

Run these commands to fix it:

```bash
# Install locales and generate en_US.UTF-8
apt-get update && apt-get install -y locales
locale-gen en_US.UTF-8

# Set environment variables
export LANG=en_US.UTF-8
export LC_ALL=en_US.UTF-8

# Make it permanent by adding to .bashrc
echo 'export LANG=en_US.UTF-8' >> ~/.bashrc
echo 'export LC_ALL=en_US.UTF-8' >> ~/.bashrc
```

Or if you want a simpler solution that doesn't require generating locales, use the minimal C.UTF-8:

```bash
export LANG=C.UTF-8
export LC_ALL=C.UTF-8

# Make it permanent
echo 'export LANG=C.UTF-8' >> ~/.bashrc
echo 'export LC_ALL=C.UTF-8' >> ~/.bashrc
```

The `C.UTF-8` locale is typically pre-installed and will stop the warnings while giving you UTF-8 support.
