From what i can remeber, there was no changes in the font size, so the symbols proir to the 7k. I can remeber checking the very first one (]) but the rest i can't remeber if i checked, but seeing that i checked the 7k one too, it makes sense that i might have been checking all along.
just as a recap
date symbol ascii value special
