Unicode is the foundation of the multilingual internet and modern technology.
Developers use Unicode to support multiple languages in applications. A single standard covers all writing systems in the world.
Typographic symbols (quotation marks, em dashes, non-breaking spaces) make text look professional. The lookup helps find the right characters.
Users decorate posts and profiles with Unicode symbols: stars ★, hearts ♥, arrows ➤, and decorative text.
Mathematical symbols (∑, ∫, ∞, ≠, ≤) and scientific notations (°, µ, Ω) are part of the Unicode standard.
Variable identifiers in different languages
Operator symbols in functional languages
Testing Unicode support in applications
Researchers use Unicode to work with phonetic transcription (IPA), historical scripts, and diacritical marks.
Braille symbols (⠃⠗⠇) are encoded in Unicode, enabling the creation of texts for the visually impaired in digital format.
