Leftwards Arrow with Stroke ↚

The Leftwards Arrow with Stroke character (↚) is a standard HTML entity defined in the HTML specification. In HTML source code, it can be written using the named entity reference ↚, the decimal numeric character reference ↚, or the hexadecimal numeric reference ↚. The character is assigned Unicode code point U+219A in the Universal Character Set.

The leftwards arrow with stroke is a left-pointing arrow crossed by a diagonal line, indicating negation or prohibition of leftward movement or reverse operation. It is used in mathematics to negate the leftward arrow's meaning and in UI contexts to indicate that backward navigation is disabled or blocked.

Arrow entities serve as directional indicators in navigation interfaces, mathematical expressions, flowcharts, and textual content throughout the web. Because they render as scalable text characters rather than bitmap images, HTML arrow entities are resolution-independent, styleable with CSS properties like color and font-size, and fully accessible to assistive technologies including screen readers.

When deciding how to encode the Leftwards Arrow with Stroke character in your HTML documents, the named entity ↚ is generally the most readable choice for developers reviewing or maintaining source code. The decimal form ↚ and hexadecimal form ↚ are equally valid alternatives that work in contexts where named entities may not be supported, or when generating HTML output programmatically from server-side code. All three representations produce identical visual output in every modern web browser.

Use the negated leftwards arrow to indicate that a reverse operation is not possible, in mathematical notation for negated implications, or in UI states where back/previous navigation is disabled. It clearly communicates that the action the plain arrow would suggest is not available.
