SERGIO HAND — Version 1.0
By Sergio Mattei · 29 October 2026

A personal handwriting font traced from Sergio's original ink on paper.

QUICK START

Install either SergioHand-Regular.ttf OR SergioHand-Regular.otf. They are the
same typeface in two outline formats; installing both is unnecessary.

macOS: open the TTF/OTF in Font Book and choose Install.
Windows: right-click the TTF/OTF and choose Install, or open it and choose Install.
Linux: install through your font viewer, or copy to ~/.local/share/fonts/.
iOS/iPadOS/Android: use an app that imports custom TTF/OTF fonts, or your
device's supported font-management workflow. Installation is app/device-specific.

WEB

Use WOFF2 with WOFF as an additional fallback. The fonts/ folder includes
SergioHand.css; keep that CSS beside the font files and import it from your site.

The font has one Regular style. Avoid synthetic bold/italic when fidelity matters:
font-synthesis: none;

WHAT IS INCLUDED

TTF: TrueType quadratic outlines for desktop/app use.
OTF: genuine OpenType CFF cubic outlines for desktop/design apps.
WOFF2 and WOFF: compressed web versions of the same glyphs and features.

119 glyphs / 116 encoded characters / 114 visible characters.
90 directly photographed characters plus 3 photographed alternate forms.
Additional encoded marks reuse those handwritten strokes, including typographic
quotes, dashes, underscore, Spanish accents and inverted punctuation. Space and
nonbreaking space share a spacing glyph. See fonts/coverage.json for exact
coverage and per-glyph provenance.

No ampersand, square brackets, braces, caret, grave accent or vertical bar was
supplied. These are not covered by this release. Unsupported text will use your
application's fallback font. The website tester identifies unsupported characters.

All source shapes were isolated from the clearest close-up, IMG_8071.HEIC;
IMG_8068, IMG_8070 and IMG_8072 were consulted as reference views of the same
sheet. The notebook grid, page headings and personal notes are not included.
Outlines are scalable vectors. The original photographed ink resolution limits
how much fine stroke detail can be recovered; the source PNGs retain that scale.

ALTERNATES

ss01: second photographed slashed zero.
ss02: first photographed cursive z.
ss03: second photographed cursive z.
Use one z alternate at a time. For example, on the web:
font-feature-settings: 'ss01' 1, 'ss02' 1;

There are no ligatures in this release. The UFO and features.fea are ready for
adding real handwritten ligature outlines later.

EDITABLE SOURCES

SergioHand-sources.zip contains:
- UFO 3 font source with Unicode mapping, spacing and feature code.
- Individual SVG outlines in font coordinates, with correct holes/counters.
- Transparent PNG isolations of the 93 photographed forms at source resolution.
- Normalized cubic outlines JSON, provenance and character coverage.
- Build and validation scripts, requirements and these notes.

SVG and PNG filenames begin with unique numeric prefixes to avoid uppercase/
lowercase filename collisions on macOS and Windows. The glyph name follows.
Original photographs remain local and are not part of any website or download.

BUILD FROM EDITABLE OUTLINES

Python 3.12 is used. In the extracted source project:
python3 -m venv .venv
.venv/bin/python -m pip install -r requirements.txt
.venv/bin/python scripts/build_font.py
.venv/bin/python scripts/validate_fonts.py

The normalized sources/outlines.json is sufficient to reproduce every font.
For source editing in a font editor, open sources/SergioHand-Regular.ufo;
export from your editor after changes. build_font.py deliberately builds from
outlines.json, so changes made only in the UFO are not consumed by that script.
isolate.py and trace_glyphs.py document the original extraction pipeline; they
require the original photograph and local work masks, which are kept private.

QUALITY CHECKS

All four exported binaries were reopened, decompiled, recompiled and reshaped
with FontTools and HarfBuzz. Character maps match across formats. Glyph bounds
fit Windows and typographic metrics. TTF and OTF specimens were visually reviewed,
and the actual WOFF2 was checked in the website. Cross-device OS installation
has not been tested on every platform.
