I am a Greek translator, and would like to translate this project into Greek. I have translated qbittorrent using the QT platform and jfilecrypt (although that was a while ago).
If you're interested, let me know
If its something that you can see being used then that would be good but I don't expect there to be a big audience for this. ScintillaDoc.html is large (400K), full of developer jargon and changes occur most months. Maintaining documentation can be a lot of ongoing work.
I'd guess that there would be fewer than 50 Greek-speaking programmers developing with Scintilla. Unless this is being done to help students (and its unlikely Scintilla is being used by secondary or early tertiary school students) then its probable that they know enough English to read technical documents.
If you do this, I'll include a link from the main documentation. In the past, there was a Japanese translation and also some Russian documentation.
