Worked on enhancing the Eclipse SUMO Python Tools repository by delivering Traditional Chinese UI localization updates. Focused on improving translation accuracy and refining localization metadata to ensure consistent and fluent user interface presentation across modules. Utilized PO language files and integrated Weblate into the translation workflow, streamlining future update cycles and supporting broader Traditional Chinese adoption. Applied internationalization and localization skills to reduce user friction and improve accessibility for Chinese-speaking users. No critical bugs were addressed during this period, with efforts concentrated on feature development and workflow improvements. The work contributed to a more inclusive and user-friendly software experience.
