U+0030 "0" Digit Zero Unicode Character
Unicode Version 17.0
0
U+0030 "0" Digit Zero is a fundamental numerical glyph representing the value of nothing, and it is encoded in the Basic Latin block (ASCII range) of the Unicode standard. It appears as a simple circular or oval shape in most fonts and is used universally in writing numbers within decimal systems, dates, times, and electronic data. While visually distinct from the capital letter "O" in professional typefaces, the digit zero often includes a dot, slash, or other variation to prevent confusion, though its standard form remains the plain circle.
