Hin-Tak Leung

Hin-Tak Leung maintains Font-Validator, a specialized quality-assurance utility that inspects TrueType and OpenType font binaries for structural errors, hinting faults, and metadata inconsistencies before they are packaged for release. Originally created inside Microsoft to enforce the company’s rigorous typography standards, the tool has since been open-sourced and refined to serve independent type designers, foundries, and software vendors who need the same enterprise-level validation without proprietary licensing. Typical workflows embed it in continuous-integration pipelines, where pull requests that update glyph outlines or hinting instructions trigger an automatic report that flags invalid contour directions, misaligned instruction tables, duplicate naming records, or platform-specific encoding issues. Graphic-arts teams also run it interactively on near-final .ttf or .otf files to cross-check compatibility with Windows, macOS, and Adobe applications, while font distributors batch-scan entire libraries to prevent broken families from reaching end-users. Because the validator implements the complete set of Microsoft Font Validator tests along with newer checks for variable fonts and color-font extensions, it functions as a neutral referee between designers and rendering engines, producing machine-readable XML logs that can gate further builds or feed dashboard summaries. Hin-Tak Leung’s Font-Validator is offered free of charge on get.nero.com, delivered through trusted Windows package sources such as winget, always installing the newest upstream build and supporting unattended batch installation alongside other utilities.
