The keyboard character ^, modifier circumflex ˆ, and combining circumflex ◌̂ all share a familiar roof-like shape, but they are different Unicode characters and behave differently in text.
There is an additional naming complication: ^ is widely called a caret in computing, while its formal Unicode name is CIRCUMFLEX ACCENT. Unicode also encodes separate characters named CARET and CARET INSERTION POINT.
Caret and Circumflex Characters at a Glance
| Symbol | Unicode name | Code point | Typical role |
|---|---|---|---|
| ^ | CIRCUMFLEX ACCENT | U+005E | Keyboard symbol, technical syntax, plain-text exponent notation |
| ˆ | MODIFIER LETTER CIRCUMFLEX ACCENT | U+02C6 | Spacing modifier used in phonetic and linguistic notation |
| ◌̂ | COMBINING CIRCUMFLEX ACCENT | U+0302 | Diacritic attached to a preceding character |
| ‸ | CARET | U+2038 | Separate caret character |
| ⁁ | CARET INSERTION POINT | U+2041 | Proofreader’s insertion mark |
These characters are a good example of why familiar keyboard names do not always match formal Unicode names. Similar naming and look-alike problems occur throughout punctuation and technical symbols.
What Is the Keyboard ^ Character?
^ is U+005E CIRCUMFLEX ACCENT.
Unicode notes that it is a spacing character and that it is known informally as a caret. It is part of ASCII and is available directly on many keyboards.
U+005E has acquired many technical uses, including:
- ASCII-based exponent notation;
- programming operators;
- regular expressions;
- markup and command syntax;
- control-character notation;
- other application-specific conventions.
The meaning depends on the system using it.
Why Is ^ Called a Caret?
The name caret is firmly established in computing and keyboard terminology, even though Unicode formally names U+005E CIRCUMFLEX ACCENT.
This creates an important distinction between a common name and a Unicode character name.
When someone says “type a caret,” they usually mean:
^
But a Unicode lookup for the formal character name CARET leads to a different code point.
What Is U+2038 CARET ‸?
‸ is U+2038 CARET.
It is a separate Unicode character from the keyboard ^. Its representative glyph is lower than the ordinary spacing circumflex and resembles a traditional caret mark.
Unicode’s current NamesList gives the character the name CARET and cross-references related arrowhead and circumflex-like characters, but it does not make U+2038 interchangeable with U+005E.
What Is the Caret Insertion Point ⁁?
⁁ is U+2041 CARET INSERTION POINT.
Unicode explicitly identifies it as a proofreader’s mark meaning “insert here.”
This is the character that should be distinguished from both:
^ — U+005E CIRCUMFLEX ACCENT
and:
‸ — U+2038 CARET
| Symbol | Name | Code point |
|---|---|---|
| ^ | CIRCUMFLEX ACCENT | U+005E |
| ‸ | CARET | U+2038 |
| ⁁ | CARET INSERTION POINT | U+2041 |
What Is the Modifier Letter Circumflex ˆ?
ˆ is U+02C6 MODIFIER LETTER CIRCUMFLEX ACCENT.
It is a spacing modifier character used in phonetic and linguistic notation. Unicode records uses including rising-falling tone, falling tone, and secondary stress.
Because it occupies its own character position, it behaves differently from a combining circumflex placed directly above a base letter.
^ vs ˆ
These two can look nearly identical:
^ — U+005E CIRCUMFLEX ACCENT
ˆ — U+02C6 MODIFIER LETTER CIRCUMFLEX ACCENT
Both are spacing characters, but they belong to different parts of Unicode and have different typical roles.
U+005E is the familiar ASCII keyboard character. U+02C6 is a modifier used in linguistic notation.
What Is the Combining Circumflex ◌̂?
U+0302 is COMBINING CIRCUMFLEX ACCENT.
Unlike ^ or ˆ, it is a combining mark. It attaches to the preceding base character rather than taking an ordinary independent spacing position.
For example:
a + ◌̂ → â
The circumflex is rendered above the preceding letter.
Combining Circumflex vs Precomposed Letters
Some letters with circumflex accents also have precomposed Unicode characters.
For example, â can be encoded as the single character U+00E2 LATIN SMALL LETTER A WITH CIRCUMFLEX.
It can also be represented as the canonically equivalent sequence:
a U+0061 + U+0302 COMBINING CIRCUMFLEX ACCENT
Unicode normalization can treat those canonical representations as equivalent.
This is different from:
a^
which contains a literal U+005E spacing character after the letter.
Why a^ Is Not the Same as â
Compare:
a^
â
The first contains:
U+0061 LATIN SMALL LETTER A + U+005E CIRCUMFLEX ACCENT
The second contains:
U+0061 LATIN SMALL LETTER A + U+0302 COMBINING CIRCUMFLEX ACCENT
The first is a sequence of two spacing characters. The second uses a combining mark attached to the base letter.
Why ^ Is Used for Exponentiation
Unicode explicitly notes that U+005E is used in ASCII-based representations of exponentiation.
For example:
2^8
is commonly understood in some technical systems as “2 raised to the eighth power.”
This is a plain-text convention, not a universal rule for every programming language or mathematical system.
Exponentiation Depends on the Programming Language
Different languages use different syntax.
Some systems use ^ for exponentiation. Others use forms such as:
**
In still other programming languages, ^ has a different meaning, such as bitwise XOR.
It is therefore inaccurate to say that the caret universally means “power” in programming.
Caret ^ in Regular Expressions
Regular-expression systems frequently assign special meanings to ^.
In common regex dialects, it may anchor a pattern to the beginning of a line or string, while in certain character-class positions it may indicate negation.
The exact behavior depends on the regular-expression dialect. These are software conventions assigned to U+005E, not meanings defined by Unicode.
Caret ^ in Programming
Programming languages use U+005E for a variety of operations.
Depending on the language, ^ can represent:
- bitwise XOR;
- logical operations;
- exponentiation;
- pointer-related syntax;
- type or annotation syntax;
- other language-specific operations.
The correct interpretation comes from the language documentation.
Circumflex as a Diacritic
A circumflex accent appears above letters in a number of writing systems and orthographies.
Examples include:
â ê î ô û
Its linguistic meaning varies by language. A circumflex may relate to vowel quality, length, tone, historical spelling, or another orthographic distinction.
The shared roof-like shape therefore does not imply one universal linguistic meaning.
Circumflex in Vietnamese
Vietnamese uses circumflex-bearing vowel letters including:
â
ê
ô
These vowels can also carry Vietnamese tone marks. Depending on the Unicode representation, text may use precomposed characters where available or canonically equivalent combining sequences.
This is different from typing an ASCII caret after the vowel.
What Is the Up Arrowhead ⌃?
Another similar character is:
⌃ — U+2303 UP ARROWHEAD
Its glyph can resemble a wide circumflex or caret, but it is a separate technical symbol.
Unicode cross-references it with U+005E, U+02C4, U+2038, and U+2227 because of their visual similarity.
What Is Modifier Letter Up Arrowhead ˄?
Unicode also contains:
˄ — U+02C4 MODIFIER LETTER UP ARROWHEAD
It is a modifier letter used in phonetic notation, including for raised articulation.
It should not be confused with the ASCII circumflex or the mathematical logical-AND symbol.
Caret ^ vs Logical AND ∧
Another important look-alike is:
∧ — U+2227 LOGICAL AND
Compare:
^ — U+005E CIRCUMFLEX ACCENT
∧ — U+2227 LOGICAL AND
The mathematical symbol is designed as an operator, while U+005E is the ASCII spacing character. They are separate Unicode characters even when a font makes their shapes look similar.
Why Font Design Makes Circumflex-Like Characters Confusing
Many of these symbols are built from the same basic inverted-V shape.
A font can vary their:
- width;
- height;
- stroke angle;
- vertical position;
- spacing.
At small sizes, ^, ˆ, ˄, and ⌃ may be difficult to distinguish visually.
Why the Difference Matters in Search and Data
Software treats these as separate characters:
^ — U+005E
ˆ — U+02C6
◌̂ — U+0302
‸ — U+2038
⁁ — U+2041
The distinction can affect:
- search;
- text normalization;
- linguistic data;
- source code;
- regular expressions;
- string comparison;
- copy and paste.
How to Tell Which Circumflex-Like Symbol You Have
Start with how the mark behaves and where it appears:
- A standalone keyboard character is likely U+005E ^.
- A spacing modifier in phonetic text may be U+02C6 ˆ.
- A mark attached directly above a preceding letter may be U+0302 COMBINING CIRCUMFLEX ACCENT or part of a precomposed accented letter.
- A character explicitly named CARET may be U+2038 ‸.
- A proofreading insertion mark may be U+2041 ⁁.
- A mathematical wedge may instead be U+2227 ∧.
If the symbol comes from copied text and its identity is unclear, paste it into What Is This Symbol and inspect the exact Unicode character.
The Main Difference
- ^ is U+005E CIRCUMFLEX ACCENT, widely called the caret in computing;
- ˆ is U+02C6 MODIFIER LETTER CIRCUMFLEX ACCENT;
- U+0302 is COMBINING CIRCUMFLEX ACCENT and attaches to a preceding character;
- ‸ is U+2038 CARET, a separate Unicode character;
- ⁁ is U+2041 CARET INSERTION POINT, explicitly documented by Unicode as a proofreader’s insertion mark;
- ∧ is U+2227 LOGICAL AND, a mathematical operator.
The shared roof-like shape makes these characters easy to confuse, but their Unicode identities, spacing behavior, and intended roles are different.
