I experience reading similarly to you. I will often become familiar with written words before I know how to pronounce them. When I want to say the word for the first time, I will have to pause and think about how it would sound out loud.
This is especially true of code and symbols. For example, consider this poem
> is it already too dark
> to play tennis with a racket
> i asked?
> while I code with [
and contrast with this one
> The house filled with laughter
> from mother and daughter
> Both were fiends
> but neither friends
or even better, combine the two
> I never used a ~
> as well as Oscar Wilde
