Early Cyrillic alphabet
[1]Unlike the Churchmen in Ohrid, Preslav scholars were much more dependent upon Greek models and quickly abandoned the Glagolitic scripts in favor of an adaptation of the Greek uncial to the needs of Slavic, which is now known as the Cyrillic alphabet.The earliest Cyrillic texts are found in northeastern Bulgaria, in the vicinity of Preslav—the Krepcha inscription, dating back to 921,[10] and a ceramic vase from Preslav, dating back to 931.[11] The systematization of Cyrillic may have been undertaken at the Council of Preslav in 893, when the Old Church Slavonic liturgy was adopted by the First Bulgarian Empire.[1] The early Cyrillic alphabet was very well suited for the writing of Old Church Slavic, generally following a principle of "one letter for one significant sound", with some arbitrary or phonotactically-based exceptions.A comprehensive repertoire of early Cyrillic characters has been included in the Unicode standard since version 5.1, published April 4, 2008.In addition to the basic letters, there were a number of scribal variations, combining ligatures, and regionalisms used, all of which varied over time.[3] Several diacritics, adopted from Polytonic Greek orthography, were also used, but were seemingly redundant[3] (these may not appear correctly in all web browsers; they are supposed to be directly above the letter, not off to its upper right): Punctuation systems in early Cyrillic manuscripts were primitive: there was no space between words and no upper and lower case, and punctuation marks were used inconsistently in all manuscripts.
