Consolas

Consolas is a monospaced typeface designed by Luc(as) de Groot. It is a part of the ClearType Font Collection, a suite of fonts that take advantage of Microsoft's ClearType font rendering technology. It has been included with Windows since Windows Vista, Microsoft Office 2007 and Microsoft Visual Studio 2010. It is the only standard Windows Vista font with a slash through the zero character. It is the default font for Microsoft Notepad starting with Windows 8.

Sans-serif faces work well for headings, captions, children's books and modern nonfiction. For long-form body text in print, most designers still prefer a serif.

Commercial typefaces require a licence that covers embedding in PDFs and ebooks; check the foundry's licence before you publish.
