U+1E8D "ẍ" Latin Small Letter X with Diaeresis Unicode Character

U+1E8D "ẍ" Latin Small Letter X with Diaeresis is a modified version of the standard lowercase X, distinguished by two dots, or diaeresis, placed above it. This character is primarily used in specific linguistic and transliteration contexts, such as in the writing of certain Indigenous languages of North America and in scholarly romanizations of languages like Kurdish, where it represents a voiced velar fricative sound similar to the "g" in Spanish "agua" or the voiced equivalent of the "ch" in Scottish "loch." Its inclusion in the Unicode standard ensures consistent digital representation and processing across different platforms and fonts.
