Font
Embed document fonts in the current file.
Consider embedding fonts when your document use rare or custom fonts not generally available in other computers.
Font embedding
Embed fonts in the document
Mark this box to embed document fonts into the document file, for portability between different computer systems. All fonts referenced in styles or direct formatting are embedded, even if the style is not applied in the document.
Only embed fonts that are used in the document
Mark this box to embed fonts used in the document and filter out unused fonts. The fonts are embedded if they are used in an applied style or in direct formatting only.
The document with embedded fonts has a larger size and the fonts are used on the target computer for better rendering of the document layout.
Font scripts to embed
Latin, Asian and Complex fonts
Check the appropriate font script to embed in the document.
Font licenses may restrict embedding fonts in documents. Font files contain flags that indicate if and how they can be embedded within a document file. LibreOffice parses these flags and determines if and how it may be embedded in a document file, and when you open a document containing embedded fonts, it will also look at these flags to determine if and how a document can be viewed or edited.
