    Universal Character Names (UCNs) are a popular and effective shorthand
    notation for representing Unicode characters. A UCN is not, however,
    "identical" to the character it represents, in the sense that a
    precomposed character is "identical" to a base character plus combining
    mark(s). It is an ASCII escape sequence and is treated like any other
    sequence of ASCII characters.

    But it's *not* a right-to-left character. It's a sequence of six LTR
    characters that *represents* a RTL character.

    Asking a text editor to display the ASCII sequence "\u05c0" as RTL, but
    to display the ASCII sequences "\x05c0" and "/u05c0" and "\uO5cO" (with
    capital letters O) and "\u04c0" as LTR, just seems bizarre and would
    surely be more confusing than the current state of affairs.

    Then you should go ahead and convert the UCN sequence to a real NUN
    (resulting in כי יהוה עיניו משטטות בכל הארץ). This is supremely easy in
    UniPad; there's even a toolbar button for it.
