Avro Keyboard

Avro Keyboard (Bengali: অভ্র কিবোর্ড) is a free and open source graphical keyboard software developed by OmicronLab for Microsoft Windows, Linux, and macOS. Several other applications have adapted its phonetic layout for Android and iOS operating systems. It is the first free Unicode and ANSI compliant Bengali keyboard interface for Windows. It was published on the 26 March 2003, which is notably Bangladesh's Independence Day. Avro Keyboard has support for fixed keyboard layout and a phonetic layout named "Avro Phonetic", which allows typing Bengali through romanized transliteration. Additional features include auto correction, spell checker, a font fixer tool to set the default Bengali font, a keyboard layout editor, a Unicode to ANSI converter, an ANSI to Unicode converter, and a set of Bengali Unicode and ANSI fonts. This software is provided in a Standard Installer Edition and a Portable Edition for Windows. Development of Avro Keyboard began in 2003 by Mehdi Hasan Khan, a student from Mymensingh Medical College. It was first published on the web for free download on 26 March 2003 under the Creative Commons Attribution-NoDerivs 3.0 Unported License. Initially, it was developed in Visual Basic, which was later transferred to Delphi.
