--- Comment #3 from V Stuart Foote <vstuart.foote at utsa.edu> ---
Our native StarMath, and MathML in general, provide limited support for
Presentation Markup of Arabic mathematical notation. Only the Content Markup
needed for standard mathematical notation.

ICU libs Unicode bidi is functional for literal strings, but literal formulas
as in OP simply need to be entered in line with text in the module in use.

Would require dev effort to refactor the sm Formula editor to provide logic
needed to handle localized literal formula input and localized Presentation
martup of formulas.
