Note for Windows Users

If you encounter issues with character encoding — such as misrepresentation of “plusminus” (±) or “sigma” (σ) symbols in the benchmark results — it’s likely due to Windows using UTF-16 LE encoding by default. To ensure characters are displayed correctly, switch your system to UTF-8:

1. Open Control Panel.
2. Navigate to Region > Administrative tab.
3. Click Change system locale….
4. Check Beta: Use Unicode UTF-8 for worldwide language support.
5. Click OK and restart your computer if prompted.

This setting configures your system to use UTF-8 encoding for non-Unicode programs, which resolves character display issues in the benchmark output.
