description: Preservation of bit-level encoding

28. Else,
a. NOTE: If srcType and targetType are the same, the transfer must be
performed in a manner that preserves the bit-level encoding of the
source data.
b. Repeat, while targetByteIndex < limit
i. Let value be GetValueFromBuffer(srcBuffer, srcByteIndex, "Uint8").
ii. Perform SetValueInBuffer(targetBuffer, targetByteIndex, "Uint8",
value).
iii. Set srcByteIndex to srcByteIndex + 1.
iv. Set targetByteIndex to targetByteIndex + 1.
