Split two texts into an array of strings.  Reduce the texts to a string of hashes where each
Unicode character represents one line.

@param string $text1 First string.
@param string $text2 Second string.

@return array Three element array, containing the encoded text1, the encoded text2 and the array
of unique strings.  The zeroth element of the array of unique strings is intentionally blank.
