x25B6

x25B6 commonly refers to the Unicode code point U+25B6, the BLACK RIGHT-POINTING TRIANGLE. It is a geometric shape that appears as a solid wedge pointing to the right and is widely used as a symbol in digital interfaces and diagrams.

Code point and classification: U+25B6 is part of the Geometric Shapes block in the Unicode standard. The glyph’s exact appearance can vary between fonts, but it is typically rendered as a filled right-pointing triangle. A closely related, lighter variant exists as U+25B7, the WHITE RIGHT-POINTING TRIANGLE, which provides a non-solid outline version for different visual contexts.

Encoding and representation: In Unicode text, the character is encoded as U+25B6. It can be represented in HTML as the hexadecimal entity ▶ or the decimal entity ▶. In many fonts and systems, it is treated as the standard play symbol and used beyond simple geometric decoration.

Usage and applications: The symbol is most recognizable as a play button in media players and streaming interfaces. It also serves as a forward indicator or directional cue in user interfaces, diagrams, and lists. Its simple geometric form makes it versatile across languages and icons sets.

Accessibility and rendering notes: When used as a control icon, it is important to provide accessible text labels (for example, “play”) for screen readers and keyboard accessibility. Rendering can differ by font, size, and rendering engine, so designers often test its visibility against backgrounds and alongside other icons.
