Where the character set is limited to ASCII, the IEEE 260.1 standard recommends using the unit name "ohm" as a symbol instead of Ω. In the electronics industry it is common to use the character R instead of the Ω symbol, thus, a 10 Ω resistor may be represented as 10R.
Characters that fall in the "political or religious" category are given the "general category" So, which is the catch-all category for "Symbol, other", i.e. anything considered a "symbol" which does not fall in any of the three other categories of Sm (mathematical symbols), Sc (currency symbols) or Sk (phonetic modifier symbols, i.e. IPA signs ...
The 33 characters classified as ASCII Punctuation & Symbols are also sometimes referred to as ASCII special characters. Often only these characters (and not other Unicode punctuation) are what is meant when an organization says a password "requires punctuation marks".

[5] The set includes all printable ASCII characters as well as some accented letters (), Greek letters, icons, and line-drawing symbols.
In HTML and XML, a numeric character reference refers to a character by its Universal Character Set/Unicode code point, and uses the format: &#xhhhh;. or &#nnnn; where the x must be lowercase in XML documents, hhhh is the code point in hexadecimal form, and nnnn is the code point in decimal form.
Unicode aims at encoding graphemes, not individual "meanings" ("semantics") of graphemes, and not glyphs.It is a matter of case-by-case judgement whether such characters should receive separate encoding when used in technical contexts, e.g. Greek letters used as mathematical symbols: thus, the choice to have a "micro-sign" µ separate from Greek μ, but not a "Mega sign" separate from Latin M ...
The symbol for the highest power level of a PSI attack in the Mother/EarthBound games; A symbol used by U.S. citizens in the 1960s & 1970s to denote resistance to the U.S. war in Viet Nam.

The following table lists many common symbols, together with their name, how they should be read out loud, and the related field of mathematics. Additionally, the subsequent columns contains an informal explanation, a short example, the Unicode location, the name for use in HTML documents, [1] and the LaTeX symbol.
