Worked on enhancing localization for the gristlabs/grist-core repository, focusing on expanding Simplified Chinese support across both server and client interfaces. Delivered new translations for admin notifications and a broad set of UI strings, improving accessibility and onboarding for Chinese-speaking users. Utilized JSON for translation files and leveraged Weblate to manage the internationalization workflow, coordinating updates across frontend and backend pipelines. The work emphasized cross-repository collaboration and careful integration of i18n strategies, resulting in measurable progress toward full localization coverage. No bugs were addressed during this period, with efforts concentrated on feature development and readiness for broader international adoption.
