  or (e.g. with LatinModern fonts) be rendered as *upright* Å
    · similar to other text-only commands (like \aa, \OE, \oe, ...)
  (i.e. no change to the LaTeX export but consistent handling in the GUI).

  - at the cost of non-consistent handling of text macros,
  
  - with the symbol in the GUI identic to what you get by inserting a literal
    Unicode character but different LaTeX output 
    (\textit{\AA} vs. \mathring{A}).
