The short version
- 1One code point can permit typographic and pictorial rendering.
- 2Variation selectors travel with the base character.
- 3Platform artwork can vary without changing the Unicode identity.
The boundary is not simply old versus new
Unicode contains emoji characters, emoji sequences, and many older symbols that can participate in emoji presentation. A heart, sun, or airplane may have both text-style and emoji-style appearances depending on defaults and selectors.
Text glyphs usually inherit font size and color. Emoji presentations are typically colorful images supplied by a platform font. The underlying code points can remain the same while the rendering changes.
Presentation hints live inside the string
For standardized sequences that permit both styles, U+FE0E signals a preference for typographic rendering and U+FE0F signals a preference for pictorial rendering. Neither selector draws a mark of its own, so the base and selector need to travel together.
Software treats the selector as guidance rather than an absolute command. When a requested combination is unavailable, an application can fall back to another supported glyph.
Pick for communication
Use text symbols when alignment, monochrome styling, and typographic integration matter. Use emoji when the pictographic tone is intentional and platform variation is acceptable.
For controls, headings, and important notices, add an accessible name in ordinary language. A visual icon should reinforce the message, not be the only way to discover it.
