Upgrade 2023...
From some time ago, bash use %b in printf:
printf %b\\n \\U1F600
So you could assign a variable by using -v flag of bash's printf builtin:
printf -v smiley \\U1F600
echo $smiley
Then for showing quickly some part of unicode table:
printf %b\\n \\U1F6{{0..9},{A..F}}{{0..9},{a..f}}|paste -d\ -{,,,}{,,,}
Showing braille part:
printf %b\\n \\U28{{0..9},{A..F}}{{0..9},{a..f}}|paste -d\ -{,,,}{,,,}

Better into a little function
showU8_256() {
local i a
for a ;do
for i in {0..9} {A..F}; do
printf '\\U%05Xx: %b %b %b %b %b %b %b %b %b %b %b %b %b %b %b %b\n' \
0x$a$i \\U$a${i}{{0..9},{A..F}}
done
done
}
Then
showU8_256 1f{3,4}

Browsing unicode table
For this, after searching reliable way, I'v finally posted on SuperUser Dumping / browsing full unicode table, my python dumpUnicode script:
./dumpUnicode | grep SMIL.*SUNGLAS\\\|FONDUE
\U01F60E: '' SMILING FACE WITH SUNGLASSES
\U01FAD5: '' FONDUE
