The Project took place during the Google Summer of Code 2017.

It’s aim was to offer full support for the Greek script, including polytonic, to an existing open source typeface. Eczar was selected, an open-source type family designed by Vaibhav Singh, produced by David Březina, and published by Rosetta Type Foundry. You can view the original Github repository of the project here.


A few words about the selected typeface: Eczar has a strong personality, with five weights from Regular to Extra-Bold and can be used to set text from body copy to display. These characteristics were transferred to the Greek script as well, with the intention of providing a contemporary open source typeface with Greek support.

At the moment, not many serif fonts that support Greek are available from Google Fonts; as a result many Greek websites, that load their fonts from Google Fonts, lack of unique brand and personality. The same can be said for non-profit organizations that depend on open source projects for their daily production tasks. By adding polytonic support, the typeface becomes even more versatile, and can be used not only for multilingual webpages but also i.e. for academic reasons, for publishing houses that prefer polytonic text etc. The goal of this project is to expand the Google Fonts collection with support for the Greek script and create a repository for future reference for designers that are interested in adding Greek support in their fonts.

A pdf file with all the character sets and sample texts can be found here.
