Represent an already encoded UTF8 Char where the the lowest 8 bits is the start of the sequence. If this contains a multi bytes sequence then each higher 8 bits are filled with the remaining sequence 8 bits per 8 bits.
For example:
A => U+0041 => 41 => 0x00000041
'€ => U+20AC => E2 82 AC => 0x00AC82E2
𐍈 => U+10348 => F0 90 8D 88 => 0x888D90F0
