The Linguistics Pro font family is based on the Utopia Nova font family, issued by Andreas Nolda, copyright(c) 2015, under the SIL Open Font License (OFL), version 1.1; see at http://scripts.sil.org/ofl. Compare to Utopia Nova the encoding in the Linguistics Pro font family is completely rearranged, there are changes in the form of some glyphs, new glyphs are added.
The Linguistics Pro font family contains two models of cyrillic glyphs. The base range of the cyrillic glyphs (uni0410:uni044F) represents the modern Bulgarian letterform model. The traditional cyrillic letterform model is included as a local feature for Russian language and as a Stylistic Set 01.
The font is still under development. There will be many new glyphs, changes in the kerning, metrics an so on.
