Applications may do so. The Unicode standard does not define the meaning of
NBH or other C1 Controls, see

NBSP has defined semantics in Unicode, but it can be implemented in
different ways (it could have a glyph of its own).

ZWNJ is not an ISO-8859-1 character at all. In Unicode, it is a control
character that prevents the use of a ligature. The character to prevent line
breaking, with no other effect, is ZERO-WIDTH NO-BREAK SPACE.
Whether NBH works at all really depends on the application, and I would not
expect applications to support it in practice, irrespective of character
encodings.
