• *Preliminary note** (look http://en.wikipedia.org/wiki/Cyrillic#Romanization)

There are various systems for romanization of Cyrillic text, including transliteration to convey Cyrillic spelling in Latin characters, and transcription to convey pronunciation.

 Standard Cyrillic-to-Latin transliteration systems include:
     * Scientific transliteration, used in linguistics, is based on the Latin Croatian alphabet.
     * The Working Group on Romanization Systems of the United Nations recommends different systems for specific languages.
     These are the most commonly used around the world.
     * ISO 9:1995, from the International Organization for Standardization.
     * American Library Association and Library of Congress Romanization tables for Slavic alphabets (ALA-LC Romanization),
        used in North American libraries.
     * BGN/PCGN romanization (1947), United States Board on Geographic Names & Permanent Committee on Geographical
        Names for British Official Use).
     * GOST 16876, a now defunct Soviet transliteration standard. Replaced by GOST 7.79, which is ISO 9 equivalent.
     * Volapuk encoding, an informal rendering of Cyrillic text over Latin-alphabet ASCII.
 Characters for use with scientific transliteration:

 For scientific use scientific transliteration is favored, and also in reference books and on maps, for media transcription is preferred.
