Converts Greek beta code to Greek characters and vice versa. If you type in Greek characters, it displays the equivalent beta code characters. If you type in beta code, it displays the corresponding Greek characters.
Beta code is a system for encoding ancient Greek text using ASCII characters. It is used by certain websites (for example, the Perseus Digital Library) for searching through texts or looking up words. For more information see:
yarn install
There are Chrome and Firefox extensions available if you want to add the converter to your browser. (See the chrome_extension and firefox_extension directories for more information). There is also an HTML page in the static directory.
For the beta code conversion code, see https://github.com/zfletch/beta-code-js. For the mappings between beta code and Unicode, see https://github.com/zfletch/beta-code-json.
Right now this only implements the subset of beta code used by Perseus for their Greek texts (for example, no lunate sigma). Future versions may add a dropdown menu to select different versions of beta code and maybe different languages.
