{{Short description|Unicode code point property names and their uses}}
{{Use British English|date=January 2025}}
The [[Unicode Standard]] assigns various properties to each Unicode character and [[code point]].<ref name="Chapter4">{{cite web|url=https://www.unicode.org/versions/Unicode16.0.0/core-spec/chapter-4/|date=September 2024|title=The Unicode Standard Version 16 |publisher=The Unicode Consortium |access-date=2024-09-13}}</ref><ref name="UAX44" />

=={{anchor|Name}}Name and alias==
A Unicode character is assigned a unique ''Name'' (na).<ref name="Chapter4"/> The name is composed of uppercase letters A–Z, digits 0–9, [[hyphen-minus]] and [[Space (punctuation)|space]]. Some sequences are excluded: names beginning with a space or hyphen, names ending with a space or hyphen, repeated spaces or hyphens, and space after hyphen are not allowed. The name is guaranteed to be unique within Unicode, and can be used to identify a code point and its character. Ideographic characters, of which there are tens of thousands, are named in the pattern "{{Smallcaps|{{lc:CJK UNIFIED IDEOGRAPH}}}}-''hhhh''". For example, {{unichar|4E00}}. Formatting characters also have names: {{unichar|00A0}}.
The following Unicode categories do not have a Name value assigned: Controls (General Category: Cc), Private use (Co), Surrogate (Cs), Non-characters (Cn) and Reserved (Cn). They may be referenced, informally, by a generic or specific meta-name, called "Code Point Labels": {{not a typo|<control>, <control-0088>, <reserved>, <noncharacter-''hhhh''>, <private-use-''hhhh''>, or <surrogate>}}. Since these labels contain "<" and ">", they can never appear in a Name, which prevents confusion.

The Case value is normative in Unicode. It pertains to those scripts with uppercase and

In Greek, the letter sigma has different lowercase forms depending on where it is in a word. {{Unichar|03a3}} converts to {{Unichar|03c3}} if it is at the start or middle of a word, and converts to {{Unichar|03c2}} if it is at the end of a word.
In Lithuanian, the dot in lowercase i and j is preserved when followed by accents. For example: Í in lowercase is i̇́.<ref>
Despite the existence of {{Unichar|1E9E}}, {{Unichar|00DF}} corresponds to "SS".
