0x2463

0x2463 is the hexadecimal code point for the Unicode character U+2463, known as CIRCLED DIGIT FOUR. It is part of the Enclosed Alphanumerics block and is classified in Unicode as Other Number (No). The glyph depicts the digit four inside a circle (④) and is used to mark items or steps in a compact, icon-like form in lists, diagrams, or user interfaces. Rendering quality depends on font support; some fonts render a clean, uniform circle, while others may vary in circle stroke or alignment.

In practical encoding terms, 0x2463 corresponds to U+2463 in Unicode. HTML or XML can represent it with a numeric character reference: decimal ④ or hexadecimal ④. The character’s UTF-8 encoding is three bytes: E2 91 A3. Its usage is largely aesthetic or organizational, and it is typically chosen when circled numbers are preferred over plain digits.

Usage considerations include accessibility and semantics: screen readers will often read the symbol as “circled four” or “circled number four,” so it should not be relied upon to convey essential meaning without accompanying text. Support for Enclosed Alphanumerics varies by font and platform, which can affect readability in some contexts. Other circled digits (such as U+2460 through U+2469) serve similar purposes for different numbers.
