There’s an indication that something is there and that a font upgrade might be needed in order to view the entire document. This isn't a good comparison because the two scenarios are different. It isn't that screen readers don't recognise punctuation and symbols, it's that they're configured to ignore them (often as a conscious choice by the user). Maths and MathML is a different thing, but in terms of the punctuation and symbols used in typical content, there is a really good reason why screen readers are configured the way they are. Let's take this example: "Hello, how are you?". When configured to speak all symbols and punctuation, this is what a screen reader says: Let apostrophe s take this example colon quote How are you question quote period. That is unusable. When the screen reader is configured to speak only important punctuation (like the @ in an email address for example), then the screen reader reads it like a human would. Let's take this example: "Hello, how are you?". It pauses for the colons and commas, it elevates in pitch to signify the question, and it pauses a little longer at the full stop. Your sentence is a good example of why missing symbols are often easy to spot. This is what my screen reader announced: "...symbol that the font can’t display, the reader normally sees a or “X” character." There was an obvious gap between "sees a" and "or", so I went to explore and found the question mark in quotes. > > A sighted user can determine if it’s worth the trouble to get a new font, but at least they know it’s an option. When screen readers skip symbols, the user can’t easily determine if there is an issue. A screen reader user could choose to disable that function, but that would be the choice of the person not the technology. In many cases blind people are part of the teams that create screen readers, and so the default configurations are based on practical experience. Punctuation is also a commonly changed configuration by even the most inexperienced screen reader users.

Also the punctuation is very dependent on context. As if you are using a math or programming. The <= will mean something different than if it is used for identifying how the flow of processes goes. Such as 1 <= 3 is a maths equation. But if I say process1 <= process2 providing context of order of process means something else. I wouldn’t want the 2nd example to say less than or equal too. Also it is a lot less content to comprehend hearing <= than the full words. A screen reader user gets used to how things are spoken.
