I have used custom keyboard shortcuts for a long time, and as usual the new version of OSX Yosemite changes all the app translations to make them slightly different enough that none of them work. After going through all the shortcuts I discovered that the Spanish entries for next/previous item in Preview don't work. Here is a screenshot of the menu item:
And here is a screenshot of the option as set up in the keyboard preferences:
Despite both texts look the same (and therefore I should be able to override the default shortcut) the custom shortcut doesn't get assigned (it did in Mavericks!). My guess is that it stopped working because Yosemite uses a different unicode combination for the first letter. How can I figure out the correct unicode sequence so that the keyboard shortcut is assigned properly?
