A transliteration tool for Old Church Slavonic (Old Bulgarian) and Old Russian. Supports Old Church Slavonic font face and transliterates between Cyrillic, ISO R9, ALA-LC, HIP and UCS.
This transiteration tool was initially published in 2014 on podolak.net and later on the Danish Portal for Slavonic, Balkan and East European Studies. As I do not have the ressources to maintain the code anymore, I have decided to publish the code to anyone under the CC BY-NC-SA 4.0-licence.
Although the code is quite messy, it works without problems. There were no complaints on wrong transliterations, the different transliteration styles seem to be in order.
Just copy all files to a folder on your server/webspace and point to it with your browser. The script is ready-to-go.
