    It is so refreshing to see an accessibility article where the author acknowledges that the correct solution is to fix bugs in 7 pieces of software, rather than expecting everyone who has ever typed anything into a computer to change how they act.

      Except Unicode latin numerals aren’t exactly in common usage, so it’s not clear how this would affect “everyone who has ever typed anything into a computer”

        This is just an example of a bigger pattern. Similar problems affect math symbols that some people use for fake bold/italic, or even use of multiple emoji.

      While it may be preferable to re-use Latin letters, it leads to ambiguity which can be confusing for a screen-reader.

      Screen readers already have to solve the problem of figuring out the word is pronounced from context. That might be because the word is a homograph (a lead weight instead of to lead, for example), or because one word is emphasized over the others.

      Latin numerals are an example of that general case: figuring out pronunciation from context.

      Latin unicode numbers (which, frankly, nobody in the Western world uses) are a case that will require hardcoded special handling in every screen reader. Which will not solve a problem for any other unicode symbol or sequence of characters, like the way flags are handled in Unicode, for example.

      To me it seems vastly preferable to re-use latin letters over Unicode symbols, except for the few cases (like the non-LTR Asian languages mentioned in the document) where using the Unicode symbols is unavoidable.
