You can follow these steps to support localization when developing new features

Introduction

1. Reuse the existing text entries in /resource/l10n/zh-CN.toml when replacing hard-coded strings in a new feature.
2. If a new feature introduces new text, add the source entry to zh-CN.toml first, then add the same key to other language files and provide the corresponding translations.

Adding a New Localized Text File

1. Add the new language text file under /resource/l10n/.
2. Copy the existing keys from the other language files into the new language file.
3. Fill in the translations for the new language file.
