That’s good to know. It sounds like a generic warning could be useful for some online technical material.

That is frankly rarely going to be encountered by accident. as stated in this thread, there is a reason why at their default levels screen reading programs keep things to a minimum punctuation wise, they are for reading after all. Just as with a person not using the software, one has some advanced warning of what they are going to read, and can adjust their personal settings accordingly. > for the record, my own settings did not read the extra symbols until I activated review, which I would do because of the unique nature of the text.

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.
