Mathematical Doublestroke Capital W. Mathematical Doublestroke Capital T. Mathematical Doublestroke Capital F.

iOS and iPadOS

Hey... We've all seen it .. on Twitter .. and it might look cool for sighted folks, but it makes very little sense with VO under iOS.
I am of course talking about the Mathematical Doublestroke, insert letter, here.
Has anyone found a way around reading this font?
Or, not reading this font. :)

Oh boy do I wish that I had found a solution to this.

I simply don't have the patience. Typically I swipe on to the next tweet as soon as VoiceOver kicks in with reading these characters.

Tried a number of iOS voices, along with eloquence with JAWS, and they all read these characters.

Unfortunately, there's no way around this as this is not a font, but actually characters used in math. Not sure what branch of math uses these double strokes, but we're stuck with them.

I'm curious to see whether changing the pronunciation of the characters to regular letters makes a difference.

Bring this up with accessibility teams at the various sites as this is hella-annoying to listen to.

NVDA also reads them, even when the symbol level is at lowest. I suppose I can mess with symbols dictionary to make it not read, but I am just too lazy to do that right now.
I haven't came across this symbol that often. And, almost never as far as I know on Android.
What does the symbol mean any way? doesn't seem like I ever felt a need to write that symbol ever, even for complex equations.

Writing double stroke letters as if on a blackboard
Mathematicians need a lot of symbols for variables, constants, vectors, operators, sets, spaces, and a lot of other objects. So they use small and big Latin and Greek letters, calligraphic letters, or write upright, italic, or bold so that they can be distinguished from each other in the same document.

In a lecture, when writing on a blackboard or a whiteboard, it is difficult to write bold letters. So, double stroke letters showed up. Well, in our documents, we still can simply switch to bold, on the other hand double stroke letters for number systems are already very common. Furthermore, a typographer may like this, since it doesn't destroy the grayness of a text, in contrast to bold symbols.

Hey Kevin, I just want to thank you for explaining what this double stroke thing really is used for. Having never had the privelege of viewing math on the blackboard, I had no idea. Appreciate you sharing your knowledge here.
