    See for the proposal
    to replace the ZWNBS use of U+FEFF with a new character U+2060 WORD JOINER.

    See for current definition
    of U+FEFF stating:

    • use as an indication of non-breaking is deprecated; see 2060  instead.

    See for the definition of
    U+2060 WORD JOINER which states:

    • a zero width non-breaking space (only)
    • intended for disambiguation of functions for byte order mark
    → FEFF zero width no-break space

    U+20620 WORD JOINER should be used instead of U+FEFF if one's font and
    application supports it.
