I was thinking that if the Windows user edits the file on Windows, 
maybe Windows will write it as iso-8859. I honestly don't know.

I am positive that 8.6.6 only partially supports Unicode. I found many
characters that would not display correctly on a text widget and would 
be saved as garbled content if captured in the widget and written to 
file. I even had problems with glob and other commands when applied to 
some file names. For example, some html page I had downloaded from 
somewhere had something to do with countries and the page title had 
Unicode flags in the title, so the title and the flags carried over 
to the file name when I saved it. The complete implementation of 
Unicode begins in 8.6.10 or 8.6.13, I can't remember which, I think
it's 8.6.13.

I know that is specifically mentioned in a wikit page, I can't 
remember which one but that is not terribly relevant right now.
