Two dots (diacritic)

Diacritical marks of two dots ¨, placed side-by-side over or under a letter, are used in a number of languages for several different purposes. The most familiar to English-language speakers are the diaeresis and the umlaut, though there are numerous others. For example, in Albanian, ë represents a schwa. Such diacritics are also sometimes used for stylistic reasons (as in the family name Brontë or the band name Mötley Crüe).

  • U+0308 ◌̈ COMBINING DIAERESIS
  • U+0324 ◌̤ COMBINING DIAERESIS BELOW
  • U+07F3 ߳ NKO COMBINING DOUBLE DOT ABOVE

In modern computer systems using Unicode, the two-dot diacritics are almost always encoded identically, having the same code point. For example, U+00E4 ä LATIN SMALL LETTER A WITH DIAERESIS represents both a-umlaut and a-diaeresis. Their appearance in print or on screen may vary between typefaces but rarely within the same typeface.
