==Background==

The formal, primary Unicode name is unique over all names, only uses certain characters & format, and is guaranteed never to change. The formal name consists of characters A–Z (uppercase), 0–9, " " (space), and "-" (hyphen).

Next to this name, a character can have one or more formal (normative) '''alias names'''. Such an alias name also follows the rules of a name: characters used (A-Z, -, 0-9, &lt;space>) and not used (a-z, %, $, etc.). Alias names are also unique in the full name set (that is, all names and alias names are all unique in their combined set). Alias names are formally described in the Unicode Standard.<ref name="NameAliases">{{cite web|url=https://www.unicode.org/Public/1416.0.0/ucd/NameAliases.txt |title=NameAliases-14.0.0.txt|access-date=20212024-09-1411|date=20202024-1004-2124|publisher=The Unicode Consortium}}</ref><ref>{{cite bookweb|url=https://www.unicode.org/versions/Unicode14Unicode16.0.0/ch24.pdfcore-spec/chapter-24|title=The Unicode Standard|version=14.0.0|publisher=The Unicode Consortium|isbn=978-1-936213-29-0|date=2021}}</ref> In this sense, an abbreviation is also considered a Unicode ''name''.

==Reason to add an alias==

Line 12:

;1. Abbreviation

:Commonly occurring abbreviations (or acronyms) for control codes, format characters, spaces, and variation selectors.

:There are 353354 such aliases, including 256 aliases for variant selectors (VS-1 ... VS-256).

:For example, {{unichar|00A0|no-break space}} has alias {{smallcaps|NBSP}}.

:Presentation: in the code charts, the abbreviation is shown in a dashed box: {{Unicode alias/abbrbox|abbr=NBSP|title=no-break space}}.

Line 22:

;3. Correction

:This is a correction for a "serious problem" in the primary character name, usually an error.

:There are 2935 such aliases.

:For example, {{unichar|2118|SCRIPT CAPITAL P}} is actually a ''lowercase'' p, and so is given alias name ※ {{smallcaps2|1=※ WEIERSTRASS ELLIPTIC FUNCTION}}: "actually this has the form of a lowercase calligraphic p, despite its name, and through the alias the correct spelling is added."

:Presentation: A corrected name is preceded by symbol ※ (the [[reference mark]]<!-- {{unichar|203B|REFERENCE MARK}} -->).

;4. Alternate

:A fewFor widely used alternate namesname for formata characterscharacter.

:There is 1 such alias.

:Example: {{unichar|FEFF|ZERO WIDTH NO-BREAK SPACE}} has alternate {{smallcaps2|1=BYTE ORDER MARK}}.

Line 36:

:Presentation: These figment abbreviations are not published in Standard; the chart shows "XXX" for each informally, that is: not a unique or identifying abbreviation.
