astroglyphs_2K

OFL astrology glyph fonts built from Noto: one Unicode font for charts and the web, plus two keyboard fonts for typing in design and video apps, all sharing one set of drawings. The package adds per-glyph metrics and one-line embedding helpers, so any chart renderer gets deterministic astrology symbols instead of depending on whatever fonts the viewer has.

The good astrology fonts (Linotype Astrology Pi, AstrotypeP and friends) are proprietary and can't be bundled. astroglyphs_2K builds compact fonts from the freely-licensed Noto family instead.

pip install astroglyphs_2K

Just want the fonts? Every font is in the Out/ folder as ready-to-install TTF, OTF and WOFF2 files, with a guide to which one to use. No Python needed.

import astroglyphs_2K as ag

svg = (ag.font_face_css()                      # <style> with the embedded @font-face rule
       + f'<text font-family={ag.FAMILY!r}>☉︎ 22°♏︎ 36′ ℞</text>')

The three fonts

The key maps are in spec/astroglyph_pi.csv and spec/astroglyph_pro.csv. keys_to_unicode() converts text typed in either keyboard font back to real Unicode, so AstrotypeP-era text can be migrated.

Alternate forms are separate codepoints, default first: Pluto ♇ ⯓ ⯔ ⯕ ⯖, Uranus ♅ ⛢, Eris ⯰ ⯱, Hygiea ⚕ ⯚, Lot of Fortune 🝴 ⊗, Lot of Spirit ⦶ Ⓢ, semisquare ∠ ∟. A renderer chooses a form by codepoint (ag.alternates("pluto")).

Lots. Only lots with a glyph in use get one: the seven Hermetic lots. Fortune and Spirit use established forms; Eros, Necessity, Courage, Victory and Nemesis are drawn as their planet with a small lot index. All seven also sit in one contiguous Private Use block (U+E100–E106, Paulus order) and on the keys È–Î in both keyboard fonts. The hundreds of other Arabic parts are best shown as ⊗ plus a text label.

Codepoints, Private Use slots and key assignments are never reassigned once released; new glyphs only take empty slots.

Glyph inventory

Every glyph in Astroglyphs 2K. Character is the literal character; Unicode name is its official name, so a row is identifiable even where the character can't render.

Zodiac signs

Luminaries, planets & nodes

Points & asteroids

Aspects

Marks

Lots

Alternate forms

Astronomy & esoteric glyphs (used by AstroglyphPi)

Composed glyphs (Private Use Area)

Unicode has no codepoint for these, so they are drawn by tools/build.py and placed in reserved Private Use ranges: E000–E0FF astronomy, E100–E1FF lots.

API

• font_face_css(embed=True) → a <style> element inlining Astroglyphs 2K as a data: woff2 URI (self-contained; returns "" when embed=False).
• FAMILY → the font-family stack (embedded family first, system fallbacks after). SYM_FAMILY and TXT_FAMILY remain, with symbol and text fallbacks respectively.
• glyph(name), alternates(name), lot(name) → characters by name, e.g. glyph("scorpio"), alternates("pluto"), lot("lot of genius") (aliases resolve: Genius and Daimon are Spirit).
• keys_to_unicode(text, layout="pi" | "pro") → convert keyboard-font text to Unicode.
• glyph_metrics(ch) → (advance, ymin, ymax, xmin, xmax) in fractions of the em (ink bounding box from the outline), for laying glyphs out without guessing.
• save_fonts(dest, fonts=None, formats=("ttf","otf","woff2")) writes the installable font files; font_bytes(font, fmt) returns one file's bytes.
• Data: GLYPHS, ALTERNATES, LOTS, LOT_ALIASES, PI_KEYMAP, PRO_KEYMAP, GLYPH_METRICS, FONT_NAMES, FONT_FORMATS, OFL_ATTRIBUTION, SOURCE_FONT_VERSIONS.

Upgrading from 0.1? See the CHANGELOG: the four Astro* families became one, and the fontset= argument is gone.

Licensing

Code: MIT. Font data: SIL Open Font License 1.1 — see LICENSES/OFL.txt and astroglyphs_2K.OFL_ATTRIBUTION. The fonts are renamed so they are not distributed under a Noto Reserved Font Name. AstroglyphPi matches AstrotypeP's key layout only; every drawing comes from Noto or is composed from Noto outlines.

Rebuilding

pip install -e ".[build]"          # fonttools + brotli + skia-pathops
python tools/build.py              # fonts, src/astroglyphs_2K/_data.py, spec/*.csv and Out/
python tools/build.py --out-only   # just refresh Out/ from the committed package fonts

Everything is driven by tools/registry.py. The build is deterministic: the same vendored sources produce byte-identical outputs.
