Noto Sans variable conformance subset

This directory contains an 11,260-byte derived test fixture, not a NUIF portable-font acceptance sample. It retains U+0041 (A), U+0048 (H), U+0066 (f), U+0069 (i), U+0078 (x), U+00C5 (Å), and U+00E9 (é) while preserving the variable metadata, layout tables, and variation stores needed by conformance tests.

Google Fonts metadata identifies the family as Noto Sans, the designer as Google, and the license as SIL Open Font License 1.1. The unmodified registry OFL.txt is retained beside the derived fixture. Its copyright notice names the Noto Project Authors and declares no Reserved Font Names. This is fixture provenance and redistribution evidence, not a general-purpose legal decision.

Reproduction

Run tools/font/prepare_variable_font_corpus.py with the exact Noto Sans and Recursive source fonts and licenses from the pinned registry commit. The script requires hb-subset 14.4.0, verifies every source and license digest, and applies this operation:

hb-subset SOURCE.ttf --unicodes=41,48,66,69,78,C5,E9 --name-IDs=* \
  --name-languages=* --layout-features=* \
  --output-file=NotoSans-variable-subset.ttf

Derived font SHA-256: 0afd77effc877ff84fa7995a58c396c124514855f8084056846b54b8cb76f3ce.

The script verifies that fvar, avar, gvar, HVAR, MVAR, and STAT survive subsetting and caps the fixture at 16 KiB. Conformance gates test the derived font directly; preserving a table does not by itself prove semantic equality with the full source font.
