Worked on the KOReader project by initiating the Traditional Chinese localization of the user guide within the koreader/koreaderhub.io.git repository. Leveraged Weblate to manage the translation workflow, contributing three incremental commits that increased coverage from 11.5% to 12.6% of the guide’s 1,951 strings. Focused on improving accessibility for Chinese-speaking users by updating terminology and instructions, while maintaining documentation standards and translation references. Utilized PO files for translation and coordinated with other contributors to ensure consistency. This work laid the foundation for broader internationalization, supporting future expansion and reducing support overhead related to localization and documentation clarity.
