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.
Andreas
