Parcialmente respondendo a minha própria pergunta:
LibreOffice vem com estas fontes, como postado aqui :
E aqui estão algumas das fontes que vêm com o OpenOffice , que se encaixam em Wikipedia :
OpenOffice includes OpenSymbol, DejaVu,the Liberation fonts (from 2.4 to 3.3) and the Gentium fonts (since 3.2). Versions prior to 2.3 included the Bitstream Vera fonts. After 3.4 the GPL-licensed Liberation fonts were removed and replaced by the Apache-licensed ChromeOS fonts Arimo (sans serif), Tinos (serif) and Cousine (monospace). OpenOffice will also use the default fonts of the running operating system.
