oracle uNISTR-like UTF-16 can be written like this:
U&'\D3C9\BA85\B3C4 \B514\C2A4\D50C\B808\C774'
it's not a function, it a way of writing strings... if you need a
it probably wouldn't be hard to write.
but you can also write in UTF-8 (literal or escaped) or unicode escaped
see docs:
u&'\+021502' -- unicode
u&'\D845\DD02' -- utf16 (docs tell methis is legal with recent versions)
e'\xF0\xA1\x94\x82' -- utf8 hex escape
e'\360\241\224\202' -- utf8 octal escape
'𡔂' -- utf8 string literal
the first 2 can be intermixed as can the last three forms.

select length('𡔂'), octet_length( '𡔂' ), length('test'),
octet_length('test');
length | octet_length | length | octet_length
