ESLC Symbol Foundry13 v0.2 — Unicode token rendering / accessibility review

[אברהם ברגמן‎]

Hello MathJax Development community,

I'm sharing a small non-confidential experimental notation project for
rendering/accessibility review: ESLC Symbol Foundry13 v0.2.

It uses short Unicode sequences such as •|•, ∆|∆, {•}, ~√ and :•: as
writable surface tokens, while preserving stable semantic IDs and
ASCII fallbacks underneath.

We would value practical feedback on:
- cross-font rendering;
- MathJax/MathML representation;
- line breaking and token boundaries;
- screen-reader / speech labeling;
- copy/paste and browser behavior;
- which constructions are likely to be fragile or misleading.

We are not asking MathJax to adopt these symbols; we're trying to
design the experiment so it remains interoperable and accessible.

Technical handoff + prototype attached.

Best,
