That version of Emacs supports only BMP as written in the
documenation of utf-8 coding system.

u -- utf-8 (alias of mule-utf-8)

UTF-8 encoding for Emacs-supported Unicode characters.
It supports Unicode characters of these ranges:
    U+0000..U+33FF, U+E000..U+FFFF.
They correspond to these Emacs character sets:
    ascii, latin-iso8859-1, mule-unicode-0100-24ff,
    mule-unicode-2500-33ff, mule-unicode-e000-ffff
