Verified that existing documentation at tests/fixtures/no-mapping.md comprehensively catalogs the 3 unmapped glyphs (g001, g002, g003) with CID numbers and explanations for why they're unmapped. All acceptance criteria met - documentation already complete from previous bead bf-68f9i. Closes bf-644ci

# bf-644ci: Verify no-mapping.pdf unmapped glyph documentation
|
|
|
|
## Task
|
|
Identify and catalog unmapped glyphs in no-mapping.pdf fixture
|
|
|
|
## Verification Summary
|
|
|
|
Verified that existing documentation at `tests/fixtures/no-mapping.md` is comprehensive and accurate.
|
|
|
|
### Unmapped Glyphs Confirmed
|
|
|
|
The fixture contains exactly 3 unmapped glyphs:
|
|
|
|
1. **`/g001` (CID 0)**
|
|
- Custom glyph name not in Adobe Glyph List (AGL)
|
|
- Font `/CustomNoMap` is not a standard Adobe font
|
|
- No ToUnicode CMap present
|
|
- Should recover as "A" via Level 4 glyph shape recognition
|
|
|
|
2. **`/g002` (CID 1)**
|
|
- Custom glyph name not in Adobe Glyph List (AGL)
|
|
- Font `/CustomNoMap` is not a standard Adobe font
|
|
- No ToUnicode CMap present
|
|
- Should recover as "B" via Level 4 glyph shape recognition
|
|
|
|
3. **`/g003` (CID 2)**
|
|
- Custom glyph name not in Adobe Glyph List (AGL)
|
|
- Font `/CustomNoMap` is not a standard Adobe font
|
|
- No ToUnicode CMap present
|
|
- Should recover as "C" via Level 4 glyph shape recognition
|
|
|
|
### Verification Methods
|
|
|
|
1. **PDF Structure Verification:**
|
|
- `pdfinfo`: Confirms PDF is valid (1 page, 660 bytes, PDF 1.4)
|
|
- `pdffonts`: Shows CustomNoMap Type 1 font with Custom encoding, no Unicode mapping
|
|
- Direct PDF inspection: Confirmed encoding array `/Differences [0 /g001 /g002 /g003]`
|
|
- Content stream verification: Confirmed glyph sequence `<g001><g002><g003> Tj`
|
|
|
|
2. **Documentation Review:**
|
|
- Existing documentation at `tests/fixtures/no-mapping.md` is comprehensive
|
|
- Includes fixture overview, unmapped glyph details, font configuration, content stream
|
|
- Explains recovery strategy and why fixture exists
|
|
- All acceptance criteria met
|
|
|
|
### Acceptance Criteria Status
|
|
|
|
- ✅ Documentation file exists at tests/fixtures/no-mapping.md
|
|
- ✅ Lists 3 specific unmapped glyphs by CID/glyph name
|
|
- ✅ Explains why each glyph is unmapped
|
|
|
|
### Conclusion
|
|
|
|
The documentation was already created in a previous bead (bf-68f9i) and is accurate and complete. No additional work required.
