The Wikipedia has the following information about this codepoint:

The comma , is a punctuation mark that appears in several variants in different languages. It has the same shape as an apostrophe or single closing quotation mark (’) in many typefaces, but it differs from them in being placed on the baseline of the text. Some typefaces render it as a small line, slightly curved or straight, but inclined from the vertical. Other fonts give it the appearance of a miniature filled-in figure 9 on the baseline.

The comma is used in many contexts and languages, mainly to separate parts of a sentence such as clauses, and items in lists mainly when there are three or more items listed. The word comma comes from the Greek κόμμα (kómma), which originally meant a cut-off piece, specifically in grammar, a short clause.

A comma-shaped mark is used as a diacritic in several writing systems and is considered distinct from the cedilla. In Byzantine and modern copies of Ancient Greek, the "rough" and "smooth breathings" (ἁ, ἀ) appear above the letter. In Latvian, Romanian, and Livonian, the comma diacritic appears below the letter, as in ș.

For the notation ⟨x⟩ and /x/ used in this article, see grapheme and phoneme respectively.
