The Wikipedia has the following information about this codepoint:

Segol (modern Hebrew: סֶגּוֹל, IPA: [seˈɡol]; formerly סְגוֹל‎, səḡôl) is a Hebrew niqqud vowel sign that is represented by three dots forming an upside down equilateral triangle "ֶ ". As such, it resembles an upside down therefore sign (a because sign) underneath a letter. In modern Hebrew, it indicates the phoneme /e/ which is similar to "e" in the English word sound in sell and is transliterated as an e.
In Modern Hebrew, segol makes the same sound as tzere, as does the Hataf Segol (Hebrew: חֲטַף סֶגּוֹל IPA: [ħaˈtaf seˈɡol], "Reduced Segol"). The reduced (or ħataf) niqqud exist for segol, patah, and kamatz which contain a shva next to it.
