OpenType is a font format developed by Microsoft and Adobe that combines the features of both TrueType and PostScript fonts. It supports a wide range of characters and advanced typographic features, making it suitable for various languages and design needs. OpenType fonts can include thousands of glyphs, allowing for more creative and flexible typography. One of the key advantages of OpenType is its ability to work across different operating systems, ensuring consistent appearance and functionality. Additionally, it supports features like ligatures, alternate characters, and stylistic sets, enhancing the overall design quality in digital and print media.
