Summary
Add
\supset(Unicode U+2283, ⊃) as a native TXF3 math glyph, enabling material-implication horseshoe notation without application-specific glyph rendering.0xC4, preserving all existing glyph assignments.\supsetLaTeX command and treat it as a math relation for contextual spacing.assets/TeXFonts.8xvandassets/TeXScrpt.8xvfrom the bundled Latin Modern fonts.Validation
The regenerated AppVars passed a local TXF3 verifier:
TeXFonts.8xv: slot0xC4, advance 12, ink 10×10, offset 7004.TeXScrpt.8xv: slot0xC4, advance 9, ink 7×7, offset 4950.Both were verified as archived, structurally valid TXF3 AppVars. Native/CI test results have not yet been provided; upstream CI should run for the PR.
Motivation
The logical-implication horseshoe
⊃is commonly used in Boolean logic notation as an alternative to⇒. Providing\supsetupstream lets applications use one consistent LaTeX renderer instead of maintaining a one-off symbol implementation.
