I have been working on a (currently 80,000 word) manuscript for the last two years. When I started, I was using an older version of Word (I believe it was 2016, but not positive). My computer died last winter and now I am using Office 365 ProPlus. In many
places in my document I have used the ~ symbol (top left button on the keyboard). This symbol changed between the two versions of Word (it's a bit shorter and curvier now), and when I try to replace the old symbol with the newer one (I need them all to be
consistent), it won't allow me to do so. I cannot delete the old symbol, I cannot make it disappear in any way. I've tried backspacing over it, deleting it (it won't even allow me to highlight it), nothing works. I can type over it, but the symbol stays put.
What can I do to make these older symbols disappear? Please help, someone!
