U+00CB "Ë" Latin Capital Letter E with Diaeresis Unicode Character

U+00CB "Ë" Latin Capital Letter E with Diaeresis is a precomposed glyph that represents the letter E with two dots, known as a diaeresis or umlaut, positioned above it. This character is used primarily in languages such as French, where it indicates that the E should be pronounced separately from the preceding vowel (as in "Noël"), and in English, where it appears in borrowed words like "naïve" to denote that the E is articulated distinctly rather than forming a digraph.
