Luman Suen enhanced Unicode text extraction for OneNote files in the apache/tika repository, focusing on accurate handling of the CachedTitleString property. By aligning its extraction logic with RichEditTextUnicode, Luman improved support for non-Latin scripts, particularly Chinese characters. The work involved Java development and file parsing, with careful attention to Unicode handling and robust unit testing. A regression test was introduced to ensure ongoing reliability in text extraction, directly benefiting downstream search and ingestion pipelines. This targeted bug fix demonstrated depth in understanding both the file format and the extraction process, resulting in more consistent and reliable data quality.
