High Sierra Symbol font not available
When using TextEdit, or Pages, or Keynote, I cannot get symbols to show by selecting the Symbol font.
I can see some useful symbols by installing the menubar keyboard icon and looking at the keyboard, and that is helpful in telling me what keys to press for some common symbols.
For other math bits I can look at the Character Viewer under the Emojis and Symbols pull-down menu item and double click to transfer the item (I would have thought copy and paste should work; it does not).
So these workarounds are helpful; but is there a fault with the Symbol font in OS High Sierra? Why does that method of font selection no longer work? My computer is a brand new one and I would have thought to be uncorrupted.
