Yeah, these tests are great for finding obvious mistakes, but it can't help with improving UX past a certain point. I get the sense that a lot of vision-impaired folks are so busy fighting for bare minimum accessibility that they don't get the opportunity to ask for better UX. As an example in NVDA, go to heading level 2 "Unique Design Features", advance past the two sentences, right after "...make each one unique", you will hear "beeightohoh", text, then "oneaiaiell", text, then "eeeffpeecue", and so on. It's like Mojibake [0] for screen readers. Or maybe not - I don't know because I am sighted!

I was thinking about how I'd fix it if it were an issue. A person who doesn't have enough visual acuity to see the distinctness of the glyphs might still want to understand the specific examples of normally-ambiguous glyphs. I came up with this, but it still isn't the best and probably breaks expectations:

        <style type="text/css">
            .sr-only {
            border: 0 !important;
            clip: rect(1px, 1px, 1px, 1px) !important;
            -webkit-clip-path: inset(50%) !important;
            clip-path: inset(50%) !important;
            height: 1px !important;
            overflow: hidden !important;
            margin: -1px !important;
            padding: 0 !important;
            position: absolute !important;
            width: 1px !important;
            white-space: nowrap !important;
            }
        </style>
        <figure>
            <div>
                <span class="sr-only">(distinct glyphs)</span>B8<span class="sr-only">(out of distinct glyphs)</span>
                <span aria-hidden="true"> </span>
                <span class="sr-only">(distinct glyphs)</span>O0<span class="sr-only">(out of distinct glyphs)</span>
            </div>
            <figcaption>
                <strong>Unambiguous Letterforms<span class="sr-only">:</span></strong><br> Letters have received special care to ensure they’re legible and clear.
            </figcaption>
        </figure>
