From 5f356195958aff094475f1195e8f1c33cf674550 Mon Sep 17 00:00:00 2001 From: jedarden Date: Mon, 6 Jul 2026 17:54:13 -0400 Subject: [PATCH] feat(bf-okdnk): add CMAP output parsing and inspection - Add iter() method to ToUnicodeMap for accessing CMAP structure - Extend test_cmap_unmapped_glyph_skip to show CMAP contents - Extend test_cmap_multiple_mappings_with_unmapped_check to show mappings - Add debug output for inspection of source bytes and target chars - Add verification note at notes/bf-okdnk.md This enables inspection of CMAP output structure to verify unmapped glyphs are properly handled before implementing actual filtering logic.
