you'd do better in many cases to put the tex in alt!

and if the tex is a single character, it's really bad practice to replace it with a image!

But it might not be easy to determine which are the "many cases" (though I agree a single easily pronounceable character would be one such case), and it would be a bit inconsistent to have some of them with the TeX in the alt, and some of them not.

Do you have an example where tex in alt would be worse than '' in alt?

but aside from accessibility, using generated images in place of inline math was what I did 29 years ago. And I certainly didn't render inline "A + Bx" as an image!!

legacy formats (EPUB2, MOBI) probably won't validate but they're pretty awful anyway. I don't think the HTML5 or EPUB3 should have any problems, but if they do, it shouldn't be hard to fix.

if ppmath is used, images could be embedded for ebookmaker to use in epub2, delete for modern formats

If you have a sample with mathml for me, I can see if it's trivial or hard.

Sorry, I.ve only recently become aware of this because I hadn't set up the notifications.
@eshellman I think it is important to use an image ( or other math component) even for single letters because the html font is not under our control so could look quite different to the same letter in a math expression. The arxiv looks interesting.

@70ray If the typeface is really that important, you have a very good case for font embedding -

I suspect it may have been to avoid ebookmaker warnings, but this is undesirable, it ignores a valid issue.
