Hi,

some questions remain:

Can't see an  (ascii 160).

Assume you got some character, whose meaning in other context is formatting.

Then it's just a character, who doesn't belong to the mode, you use.

'delete-horizontal-space' is an edit-function, not designed to cure 
encoding-errors.

Presumable you got chars into a text-mode buffer, which are not text.
That may indicate a bug, but must not.
