Font embedding

Source: Wikipedia, the free encyclopedia.

Font embedding is the inclusion of

licensed
fonts to be freely distributed.

History

Font embedding has been possible with

Portable Document Format (PDF), Microsoft Word for Windows and some other applications for many years. LibreOffice supports font embedding since version 4.1 in its Writer, Calc
and Impress applications.

In word processors

Windows has permitted font embedding in some document formats since Word 97 (such as .doc or .rtf). But this feature does not work correctly in some Word versions.[1]

Both OpenOffice.org and LibreOffice support font embedding in the PDF export feature.[3]

Font embedding in word processors is not widely supported nor interoperable.[4][5] For example, if a .rtf file made in Microsoft Word is opened in LibreOffice Writer, it will usually remove the embedded fonts.[citation needed]

Controversy

Font embedding is a controversial practice because it allows copyrighted fonts to be freely distributed. The controversy can be mitigated by only embedding the characters required to view the document (subsetting). This reduces file size but prohibits adding previously unused characters to the document.

Because of the potential for copyright infringement, Microsoft Internet Explorer only permits embedded fonts that include digital rights management (DRM) protections. The Acid3 test requires font embedding with minimal DRM protections.
