Definition of Bytes
A byte is the smallest unit of storage which can be accessed in a computer's memory- either in RAM or ROM.It also holds exactly 8 bits.But its old view one byte was sufficient to hold one 8 bit character.Modern days especially on .NET or international versions of Win 32, 16 bits is needed.

In spread spectrum stuff there are 64 or 128 CHIPS per bit.
Spread Spectrum, CDMA and GPS

In standard computing there are now, bits, nibbles, bytes, words, longwords, long-longwords. These consist of 1, 4, 8, 16, 32 and 64 bits respectively.

Don't confuse byte or word with codepoints in unicode format, which is what your question implies.

Byte means 8 bits, even when memory accesses align in 128-bit chunks, even for machines that use native 16-bit UNICODE instead of ASCII.

There's probably a handful of PDP-8's still running in the world, but we don't have to worry about building new programming languages for them, so their 12-bit 'bytes' do not bother us.

Cray also experimented with weird byte-sizes. Some Cray machines had minimum sizes of 32-bits. Porting programs to them was very difficult, so I don't know of any more modern architecture which does the same. Byte access is inefficient in many modern architectures but still possible.
