How many languages use symbols instead of letters and which ones?

Several languages use symbols instead of letters, the most notable being Chinese, which employs logographic characters representing Words or morphemes. Other languages with symbolic systems include Japanese, which utilizes kanji (derived from Chinese characters) alongside syllabaries like hiragana and katakana. Additionally, languages such as Korean use a combination of symbols (Hangul) to represent sounds. Ancient scripts like Egyptian hieroglyphs and Sumerian cuneiform also relied on symbols for communication.
