Unicode encodes the symbol as U+2126 Ω OHM SIGN, distinct from Greek omega among letterlike symbols, but it is only included for backward compatibility and the Greek uppercase omega character U+03A9 Ω GREEK CAPITAL LETTER OMEGA (Ω, Ω) is preferred. [20] In MS-DOS and Microsoft Windows, the alt code ALT 234 may produce the Ω symbol.
Unicode has a separate code point U+2126 Ω OHM SIGN (HTML entity Ω), but it is included only for backward compatibility, and the canonically equivalent code point U+03A9 Ω GREEK CAPITAL LETTER OMEGA (Ω) is preferred. [9] In statistical mechanics, Ω refers to the multiplicity (number of microstates) in a system.
The Unicode Standard encodes almost all standard characters used in mathematics. [1] Unicode Technical Report #25 provides comprehensive information about the character repertoire, their properties, and guidelines for implementation. [1] Mathematical operators and symbols are in multiple Unicode blocks. Some of these blocks are dedicated to, or ...
As of Unicode version 16.0, there are 155,063 characters with code points, covering 168 modern and historical scripts, as well as multiple symbol sets.This article includes the 1,062 characters in the Multilingual European Character Set 2 subset, and some additional related characters.
[1] Exceptions to this include characters in certain writing systems that are also in use as political or religious symbols, such as 卐 (U+5350), the swastika encoded as a Chinese character (although it is also encoded as a religious symbol at U+0FD5); or ॐ (U+0950), the Om symbol which is, strictly speaking, a Devanagari ligature.

The Unicode Standard states that "The universe of symbols is rich and open-ended," but that in order to be considered, a symbol must have a "demonstrated need or strong desire to exchange in plain text." [1] This makes the issue of what symbols to encode and how symbols should be encoded more complicated than the issues surrounding writing ...
