APL Functional Symbol Up Tack Overbar Symbol
⍑ is an APL functional symbol (Unicode U+2351) used in APL code as a specific operation.
U+2351
⍑ is an APL functional symbol identified by Unicode code point U+2351. It’s primarily encountered in APL programming contexts. This page helps you understand what it is and copy it reliably across platforms.
Apl Functional Symbol Up Tack Overbar Symbol Meaning
⍑ (Unicode U+2351) is the APL “functional symbol up tack overbar.” In APL, symbols like this represent specific built-in functions rather than punctuation or decoration. The “up tack” and “overbar” components indicate a distinct operation that differs from similarly shaped APL glyphs. If you are porting or reading APL code, using the correct Unicode character is important—confusing ⍑ with a nearby symbol can change the meaning of an expression or cause errors in interpreters. Use the exact character rather than approximations to ensure consistent results.
Common uses
- •Writing or reviewing APL code that uses this specific built-in function
- •Copy/pasting APL expressions into documentation, READMEs, or notebooks
- •Searching for or indexing APL text where this symbol appears
- •Creating educational materials that reference exact APL glyphs
- •Testing font/rendering or Unicode handling for the character U+2351

FAQ
What does the Apl Functional Symbol Up Tack Overbar symbol mean?
⍑ (Unicode U+2351) is the APL “functional symbol up tack overbar.” In APL, symbols like this represent specific built-in functions rather than punctuation or decoration. The “up tack” and “overbar” components indicate a distinct operation that differs from similarly shaped APL glyphs. If you are porting or reading APL code, using the correct Unicode character is important—confusing ⍑ with a nearby symbol can change the meaning of an expression or cause errors in interpreters. Use the exact character rather than approximations to ensure consistent results.
What Unicode character is ⍑?
⍑ is the APL functional symbol up tack overbar, Unicode U+2351.
How do I copy ⍑ reliably?
Copy the symbol itself (⍑). If your environment is Unicode-aware, it will paste correctly; otherwise use the HTML entity (⍑) or the Unicode escapes (\\2351 or \\u{2351}).
Why does the exact symbol matter in APL?
APL symbols are functional tokens. Using the wrong glyph (even if it looks similar) can change what the code does or cause interpreter errors.
Where would I typically see ⍑?
You’ll mainly see ⍑ in APL code, APL learning materials that quote exact expressions, or technical text that references that specific built-in function.
