Subject: [PATCH] Refactor Marshal function in filter encoder

- Simplified the key-value appending logic in the Marshal function by replacing manual string appending with the text.AppendQuote method for better readability and maintainability.
- Updated version number to v0.19.9 to reflect the changes made.
