I believe that you could add a check in the settings, and include the mappings in a text file. In this way, anyone who would like to search in a second alphabet simultaneously will just enable the setting. And you will not only support Greek, but also any other language you want. Creating a file containing the mappings is quite simple and straightforward for any user.

Yes, that's probably what we will do, or something very like it. So although we won't support different 8-bit fonts for different tracks, or indeed any UI for selecting 8-bit fonts, those of you who've hacked your fonts will be able to hack the mappings file to match.
