The user shared with us a Mahara page showing the affected text. Looking at it in a hex viewer, I can see that the affected Greek letters are two-byte UTF-8 characters, in the parts where they're displaying correctly, and one-byte "?" characters where they're displaying incorrectly.
So that actually suggests it may not just be something like these characters getting split by an unfortunate str_replace(), but that we've got some text processing function that is filtering them out. ά : ce ac ( http://www.mclean.net.nz/ucf/?c=U+03AC ) έ : ce ad ( http://www.mclean.net.nz/ucf/?c=U+03AD ) ό : cf 8c ( http://www.mclean.net.nz/ucf/?c=U+03CC ) ? : 3f ( http://www.mclean.net.nz/ucf/?c=U+003F ) ** Attachment added: "imagetest - ATS2020.html" https://bugs.launchpad.net/mahara/+bug/1639635/+attachment/4773657/+files/imagetest%20-%20ATS2020.html -- You received this bug notification because you are a member of Mahara Contributors, which is subscribed to Mahara.

It only happens when images are involved, which suggests it's a bug in the TinyMCE embedded image processor, possibly from us failing to use multibyte string functions.
