Thanks for clarifying.
In fact, with your explanation I was able to figure out why it still wasn't working wasn't working.
When I pasted your code directly, the @ symbol did indeed change to 'at'. However, I need to unchange characters that wptexturize changes, and that wasn't working ... until I changed the 12 to a 1.
But, I can only change one character with this code.
Is there a way to change multiple characters?
wptexturize currently changes '...' to '…'
This is fine when I use an ellipsis, but I occasionally end sentences with four dots - an ellipsis plus a period to signify end of sentence (as you are supposed to do). But wptexturize changes it to the special character … followed by a period, which is larger in the font and looks silly.
So I want to have this:
change ' ... ' to ' … '
do not allow wptexturize to change '...' to '…'
I can make the first instance, but the other still exists in wptexturize, so it keeps happening.
And I can't keep the three dots. I've tried changing '...' to '...' (the same thing) but wptexturize overrides it with the …, even though I can change '...' to anything else just fine.
I hope I explained that properly! lol
