U+0313 "̓" Combining Comma Above Unicode Character

U+0313 "̓" Combining Comma Above is a diacritical mark used primarily in Greek script, where it is known as the “psili” or “smooth breathing” mark, indicating the absence of an initial /h/ sound in ancient Greek. It appears as a small comma-shaped glyph positioned above a base letter, and as a combining character, it is designed to attach to the preceding character, such as an alpha or epsilon, without taking up additional spacing. This mark is essential for classical Greek orthography and, when the system is enabled, will render above a letter in digital text, though it may not display correctly if the chosen font lacks appropriate support.
