In March of this year, the Central Bank of Turkey announced the adoption of a new currency symbol for the Turkish lira. Public use of the new currency symbol has already been adopted within Turkey.
Recognizing the urgent need to support the new currency symbol in information systems, the Unicode Consortium has scheduled its next release, Unicode 6.2, for the third quarter of 2012. That release will include the new character, U+20BA TURKISH LIRA SIGN.
Additional information regarding the new Turkish lira sign is available from the Central Bank of Turkey: http://www.tcmb.gov.tr/yeni/iletisimgm/TurkishLira.php
