Base CJK glyphs and every Ideographic Variation Sequence registered in Unicode IVD 2025-07-14 — including hard-to-find variants like 邉 E011E (Hanyo-Denshi TK01090330). Using a single typeface for every IVS means overlays in this tool compare structural differences rather than type-design drift. Glyphs are generated from GlyphWiki via the KAGE system.

Mathematical operator base glyphs (∩ ∪ ∅ etc.) and their U+FE00 SVS variants — Jigmo and the CJK fonts don't cover the U+22xx range, so Noto Sans Math is merged in for both the bare characters and their serif variants.
