BlissFont

BCI-AV → real fonts. Compiles the [BCI-AV 2025-02-15] release (6,183 symbols, 6,419 glyph records) into OpenType/WOFF2 with GPOS-anchored grammar indicators.

Live: https://aactools.github.io/BlissFont/ — sandbox, inspector, symbol hub, symbolic-web (ruby) demo, downloads. Pair repo: BlissNLP (English→Bliss pipeline).

Quickstart

uv sync
uv run python scripts/build_all.py    # fresh clone -> everything

Or step-by-step (same order):

uv run python scripts/download_data.py        # BCI-AV SVGs + xlsx + proposal PDFs
uv run python scripts/build_database.py       # -> bliss_character_data.json + SQLite
uv run python scripts/analyze_derivations.py  # + derivation_components, collation weights
uv run python scripts/map_unicode.py          # + proposed scalars -> Unibliss.txt
uv run python scripts/map_annotations.py      # + N1866 / MSBI / radical annotations
uv run python scripts/build_font.py           # outline fonts x3 weights
uv run python scripts/build_blissary_font.py  # stroke fonts x3 weights
uv run python scripts/integrate_crosswalk.py  # + Blissary B-codes (99.8%)
uv run python scripts/merge_all_languages.py  # + 18 languages, WinBliss
uv run python scripts/build_vector_db.py      # web GloVe db (50d)
uv run python scripts/build_semantic_db.py    # bliss_semantic.db
uv run python scripts/build_symbol_hub.py build
uv run python scripts/export_web_asset.py     # data/web/bliss_resolver.bin

Encoding (3 layers)

layer	range	use
official	U+16200–U+167FF (L2/23-138 chart)	~1,100 proposed scalars — always preferred
stable PUA	0xF0000 + BCI_ID	every glyph, never shifts — use this
legacy	U+E000–U+F8FF	capped at 6,400 slots, deprecated

Scripts

script	does
build_font.py / build_blissary_font.py	SVGs → OTF/WOFF2, GPOS anchors from glyph bounds
map_unicode.py	proposal PDF → Unibliss.txt (UCD format)
integrate_crosswalk.py	joins hlridge B-code crosswalk (99.8%)
merge_all_languages.py	xlsx → JSON: 18 langs + WinBliss
build_semantic_db.py	bliss_semantic.db: derivations, FTS, vectors
build_symbol_hub.py	multi-set hub (Bliss + ARASAAC/Mulberry via GlobalSymbols), ConceptNet layer, link/link2/wsd
load_conceptnet.py	ConceptNet 5.7 → 1.97M edges (server-side only)
export_web_asset.py	bliss_resolver.bin — SQLite-WASM asset for hub.html / ruby.html
fix_legacy_cmap_overflow.py	strips CJK-shadow entries from built fonts

Web pages

• index.html — workspace: sandbox, directory, keyboard, inspector, downloads, hub tab, ruby tab
• hub.html — concept resolver (search → glyph, 18 langs, derivations, cross-set links, GloVe fallback)
• ruby.html — symbolic-web demo: <ruby lang=zbl> annotation, display modes, Bliss↔ARASAAC↔Mulberry switching
