OpenType is a cross-platform font file format developed by Microsoft and Adobe. It supports both TrueType and PostScript font data, allowing for broad compatibility across different operating systems. OpenType fonts offer advanced typographic features such as ligatures, alternate characters, and support for multiple languages and scripts. These features enhance the quality and flexibility of digital typography, making OpenType a preferred choice for designers and publishers. In cybersecurity, understanding file formats like OpenType is important, as malicious actors can sometimes exploit vulnerabilities in font rendering engines to execute attacks or deliver malware.
