Thats not what I meant.

I wrote http://blog.languager.org/2014/04/unicoded-python.html
 – mostly on a debian box.
Later on seeing it on a less heavily setup ubuntu box, I see
 ⟮ ⟯ ⟬ ⟭ ⦇ ⦈ ⦉ ⦊
have become 'missing-glyph' boxes.

It leads me ask, how much else of what I am writing, some random reader 
has simply not seen?
Quite simply we can never know – because most are going to go away saying
"mojibaked/garbled rubbish"

Speaking of what you understood of what I said:
Yes invisible chars is another problem I was recently bitten by.
I pasted something from google into emacs' org mode.
Following that link again I kept getting a broken link.

Until I found that the link had an invisible char

The problem was that emacs was faithfully rendering that char according
to standard, ie invisibly!
