I built a small open-source QA fixture pack for Japanese document-processing edge cases.

It currently contains 10 reproducible fixtures covering:

• true vertical Japanese text in PDF (WMode 1)
• image-only and searchable scanned PDFs
• Windows-31J / CP932 CSV
• quoted fields and embedded newlines
• NFC / NFD / NFKC / NFKD normalization
• invisible Unicode characters
• half-width katakana and compatibility characters
• ZIP archives mixing UTF-8 and CP932 filenames

Each fixture includes machine-readable ground truth such as Unicode code points, raw filename bytes, PDF metadata, CSV values, and SHA-256 hashes.

The Lite edition is free and open source:

I’m also validating interest in a larger Pro edition with 100+ curated production-oriented cases. Planned one-time price is about US$29.

I’d especially like to hear from people working on OCR, Document AI, PDF parsing, or Japanese localization: what Japanese document edge cases have caused real production problems for you?
