I tried to install the font ubuntu for my macbook air and it works great on email... but it won't recognize ' and ".
When I type ' or " I get a superscript 8 or 9.
To turn the keyboard inch and foot marks, the "straight" quotes, into typographically correct "curly" quotes.
Curly quotes are the correct form in English punctuation. You can actually type them using the option & shift keys in conjunction with the angle bracket keys. The problem is very few people directly type the correct quotes because they are awkward to do, and to remember the combination.
Further other languages use different bracketing methods, and it is simpler to use the same method to achieve them all, by using an auto-replace method to take the correct substitution for whatever language is set in the System Preferences.
For some reason Pages 5 is taking the wrong Unicode characters instead of the curly quote glyphs.
There is obviously something wrong in the new Pages coding, it is not simply taking the Unicode addresses, because it is substituting the same wrong glyphs for both the double and single quotes.
This is not happening in TextEdit, Pages '09 or any other word processing app I can find. So quite evidently there is a very odd error in Pages 5.
