I am doing a bit of spacing lately and came across the accents. how are they spaced? In some fonts they have all the same width (Myriad) and in others they have their own width (Thesis). Whats the correct way or what are the different "philosophies" behind these two ways of spacing? Is there any rules to that or does it not even matter, since accents are hardly ever used by themselfes anyway.
Thanks for any suggestions.
