Mapping of important parts of the Universal Character Set (usually referred to as Unicode) for English Wikipedia.
The table[edit]
Script error: No such module "UCS".
Arithmetic[edit]
Addition: “+”.
Subtraction and opposite/negative: “−” (−) in text, “-” in arguments of templates.
Multiplication: “×” (×), “⋅” (⋅); no substitutes shall be used.
Division: “/” (usually), “ ⁄ ” (virtually unused), “ ∕ ” (sometimes).
Specific symbols[edit]
Asterisk[edit]
Not a multiplication sign (except in source code in some languages).
Hyphen-minus[edit]
Dual use: as a hyphen in the text and minus sign in certain wiki contexts.
Slash[edit]
Dual use: as a punctuation and as a #division sign.
Degree sign[edit]
“°” is a separate character! Shall never be substituted with “0” or “o” in superscript!
Dashes[edit]
Several flavours of, but – is the preferred.
Quotation marks[edit]
All but “ " ” and “ ' ” are frowned upon. Also, “ ’ ” is sometimes mistakenly used as a substitute for prime (′) and vice versa.
Junk characters[edit]
Standalone “accents”[edit]
Both “ ´ ” and “ ` ” are virtually useless without the overstrike feature, but are sometimes mistakenly used instead of quotation marks. Though, “`” is an ASCII character and is actually used in some scripting languages.
Superscripts and fractions[edit]
Unicode superscripts and precomposed fractions are generally discouraged. Though, they may be used in edit summaries where text formatting is unavailable.
Ordinal indicators[edit]
“º” and “ª” are useless is English language, but the former is sometimes mistakenly used as a substitute for #Degree sign.
Arrows[edit]
Left, right, and left–right arrows are very common in Wikipedia. The “⇌” symbols is used for reactions, but is rendered as image instead of the character: see {{eqm}}.
