[Dev-luatex] Imprecise language in the OpenType Math specification leading to implementation differences amongst math engines

Dear Developers of LuaTeX, I am writing this mail to report a bug in the OpenType Math specification regarding imprecise language, found by Khaled Hosny: [MATH] The algorithm for applying MathKernInfo is incorrect · Issue #1147 · MicrosoftDocs/typography-issues https://github.com/MicrosoftDocs/typography-issues/issues/1147. LuaTeX follows the letter of the specification, while XeTeX follows the intent of the specification. This has created compatibility issues for font developers. Thank you. -- Apoorv Potnis
