may i ask, what’s the definition of “variant character”?
from the link of japanese language stackexchange:
when the same Unicode codepoint has different glyphs depending on the language code selected
doesn’t it depend on the region / language settings of the operating system, and fonts installed; that apps chose the font to display the glyph of particular code point?
i’m curious.
case 1: 幕 (u+5e55) vs 幙 (u+5e59), the 教育部異體字字典 stated that 幕 is regular, and 幙 is variant 🙀

another case is 並 (u+4e26) vs 竝 (u+7add)

how would the feature requested handle these two case?
have fun :)
