If we use this feature, there must be a warning like "You are opening a binary file in a text editor, this can lead to an unexpected result and we strongly recommend that you make a backup".

I would love this. I find myself needing additional text editors (like 
scite) because geany is unable to view binary files. I think the mixed 
content example in the first email shows why geany should support it.

Is that a costly feature or what speaks against it?

Best regards.
