The problem isn't customising your editor to use the symbol you want, but to have a spec that allows freely sharing files back and forth without trouble.
Org has no specification other editors can follow (although people have tried adding support to other editors and also writing such a spec).
There is a written-down specification, but not a formal grammar (I assume you implied the latter): https://orgmode.org/worg/org-syntax.html
The standalone project, org-parser is pretty good! https://github.com/200ok-ch/org-parser (usable from Javascript, Java).
