[Bug 1639635] [NEW] Two-part UTF-8 characters in a TinyMCE text field, turned into question marks by embedded image processing

 

Public bug reported:

As reported on the forum:
https://mahara.org/interaction/forum/topic.php?id=7723&post=31207

A user reported that Greek characters with accent marks (ό έ ά) get
turned into question marks (? ? ?) if they're in a TinyMCE text box, and
the user embeds images into that text box. 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.
