I am making available a Unicode to Legacy Font conversion routine I wrote last year.
This utility culls through characters of text on the clipboard and then converts any Unicode characters that fall within the Helena font characters into their Helena font equivalencies.
This has at least two uses.
1. If you use Helena in your text document, you can easily include Greek that you are pulling from another source, even if it is in Unicode characters.
2. If you encounter some Unicode Greek text, such as on a web page, you can copy it to the clipboard and then convert it to Helena encoding, suitable for pasting into the search box of Accordance Bible software.
