[iText-questions] How to get Unicode ref from Font character index

[Alan]

Hi, I have an application that returns a Font object and a Character Index integer for point symbols.   I have worked out how to do all that is needed to write this to PDF except for how to get the Unicode value.   For example, I can use the windows charmap.exe to tell that CharacterIndex 67 is “\u005e” but I can’t figure out how to do this programmatically.   Can someone give me a clue or two, please?
