- Restart Fess application

### Translations not showing

- Clear browser cache
- Force language with `?browser_lang=[locale]` parameter
- Check property file encoding (should be UTF-8 or use Unicode escapes `\uXXXX`)
- Verify property keys match exactly with base English files

### Build errors after regeneration

- Check property file syntax (no unescaped special characters)

    depends on JUnit, though it continues to work with all testing frameworks.
 *  Fix: `FormEncodingBuilder` is now consistent with browsers in which
    characters it escapes. Previously we weren’t percent-encoding commas,
    parens, and other characters.
 *  Fix: Relax `FormEncodingBuilder` to support building empty forms.
