Recommended action

- Click on the download link below.
- Save the file to your computer.
- Extract the font file from the zip archive.
- Install the font on your system by following the standard font installation procedure.
Security and integrity risks
- Patched font files from untrusted sources can be carriers for malware: fonts are processed by system font renderers and can include exploit vectors (historical CVEs exist).
- Bundled archives often include additional executables, installers, or DLLs that execute malicious code.
- Using unknown fonts on servers (e.g., in PDF rendering, web servers, or CI pipelines) can escalate risk to multiple users or systems.
