Since 2026.39 reads `unifont 1.0` files (isocp.shx and its family among them) instead of falling back to a substitute, a glyph built from a subshape went wrong: code 7 is followed by a two-byte code point in a unifont, but only big fonts read two bytes, so the low byte ran on as a drawing opcode. ISOCP's `9` came out at x-height as a small bowl. Fixes #1556 Co-Authored-By: Claude Opus 5.5 <[email protected]>
