U+0308 Combining Diaeresis

U+0308 was added in Unicode version 1.1 in 1993. It belongs to the block U+0300 para U+036F Combining Diacritical Marks in the U+0000 para U+FFFF Basic Multilingual Plane.

This character is a Nonspacing Mark and inherits its script property from the preceding character. It is also used in the scripts Armenian, Cirílico, Duployan shorthand, Gothic, Greek, Hebrew, Latin, Old Permic, Syriac, Tai Le. El carácter es también conocido como double dot above, umlaut, Greek dialytika y double derivative.

The glyph is not a composition. Its width in East Asian texts is determined by its context. It can be displayed wide or narrow. In bidirectional text it acts as Nonspacing Mark. When changing direction it is not mirrored. U+0308 prohibits a line break before it. The glyph can be confused with 8 other glyphs.

El Wikipedia tiene la siguiente información acerca de este punto de código:

Diacritical marks of two dots ¨, placed side-by-side over or under a letter, are used in several 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).

In modern computer systems using Unicode, the two-dot diacritics are almost always encoded identically, having the same code point. For example, U+00F6 ö LATIN SMALL LETTER O WITH DIAERESIS represents both o-umlaut and o-diaeresis. Their appearance in print or on screen may vary between typefaces but rarely within the same typeface.

The word trema (French: tréma), used in linguistics and also classical scholarship, describes the form of both the umlaut diacritic and the diaeresis rather than their function and is used in those contexts to refer to either.
