diacritical marks
Marks over, under, after, or through various
letters in the alphabets of several languages,
designed to indicate the nature or stress of the
sounds they represent. While lowercase letters
having accent marks are cast as units, in display
printing it is sometimes necessary to cast accent
marks separately, i.e., the so-called floating
accents. In library binding, diacritical marks are
generally added by hand after the case has been
blocked. Commonly used marks include:
acute ´
cedilla ¸
circumflex ˆ
Umlaut (or dieresis) ¨
grave `
tilde ~
