Font embedding
Mark this box to embed document fonts into the document file, for portability between different computer systems. 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.
Consider embedding fonts when your document use rare or custom fonts not generally available in other computers.
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. Collabora Office 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.
