how to italicize specific words in a title?

Try the Find and Replace (under Edit or Ctrl+R on the PC) – but I find that I have to copy the text from somewhere where the font has already been applied in X8.1  – don’t think that was the case before?  If I try – on my PC to use the quick font attributes (like ctrl+I) it makes it invisible (both in the box and if I try to use it - as it replaces the word with invisible text.  And it doesn’t appear that font selection is possible in the menu from anywhere?  

This must be a bug?
