Shortcuts for typing ACCENT MARKS doesn't work?

Hey all.
On mavericks here and I'm realizing that the shortcuts I used to use for foreign language accent marks no longer work....

This describes how I used to do it:

To get accents on the Mac, hold down the Option key, and while holding it down, type the letter e; then release those keys and type the letter that you want the accent to appear on:

á = Opt + e, then a
é = Opt + e, then e
í = Opt + e, then i
ó = Opt + e, then o
ú = Opt + e, then u
For the ñ, hold down the Option key while you type the n; release and type n again.

ñ = Opt + n, then n




What setting needs to be switched on/off for these shortcuts to work while writing text? thanks!

 

Weird, in System prefs>inputs it was set to unicode hex, whatever that is! I changed back to english and now they work!

Danke Schön!
