pub fn feature_icon(kind: &str) -> Option<char>Expand description
The custom BrepIcons glyph for a feature type, if one exists. Every kernel
feature type has a FreeCAD-inspired monoline glyph in the font’s Private-Use
block starting at U+E030 (edited as tools/iconfont/glyphs/*.svg). The font is
installed as family "brep_icons" at the HEAD of egui’s fallback chain
(crate-side fonts.rs), so a bare returned char renders as the icon.
Matches the SAME alias set the kernel dispatch does (short codes AND the
long-/class-name strings saved files carry — e.g. "CHAMFER", the misspelt
"DATIUM", "PUSH FACE"), uppercased, so a type loaded from disk resolves.
