Troubleshooting

Sorry to see you here. Terminals can be finicky.

Common Problems

  1. Key Bindings
  2. Copy-Paste
  3. Appearance (Colors and Fonts)
  4. Locale (Number formatting)
  5. Windows Timezone Database
  6. DuckDB Version Mismatch

While Harlequin aims to work in every terminal, some do provide better support for Harlequin’s features. Our recommended terminals can be found here.
