Private Use Area

The paper proposes an encoding standard for early Cyrillic characters and glyphs that are still missing in the Universal Character Set (UCS) of the Unicode Standard and for different reasons will probably never be included, but are nevertheless used by the paleoslavistic community. This micro-standard is meant to expand, not to replace the Unicode standard and follows the path chosen by the Medieval Unicode Font Initiative (MUFI) a few years ago for the Latin script (see http://www.hit.uib.no/mufi/). Starting from the inventory of Old Cyrillic originally proposed at the conference held in Belgrade on 15–17 October 2007 (see BP), and taking in view the recommendations given by Birnbaum et al. 2008 and the MUFI-consortium, the chosen set is limited to 178 units with a specific function (characters and composites, superscript characters, modifier characters, and punctuation marks), which are located in the Private Use Area (PUA). Their positions (code points) are coordinated with MUFI. This set we will call PUA1. In the future a second set PUA2 will be proposed for a number of ligatures and paleographic variants that may not be coordinated with MUFI and are intended for special publications addressed to Slavistic readers. It is hoped that the proposed PUA encoding for Early Cyrillic Symbols, for which we choose the abbreviation CYFI, will establish itself as a sort of micro-standardization. Designers of scholarly fonts are encouraged to include these symbols according to this proposal (see code points in the appendix).
