ABSTRACT:
The present encoding method encodes binary data as sequences of code points occupying the Private Use Area of the Unicode Basic Multilingual Plane. The encoded data can be contained within a stream of UTF-8, UTF-16 or UTF-32 code units and subsequently decoded to yield the original binary data. This method requires minimal processing for both encoding and decoding operations, and yields a 75% storage efficiency limit. Each datum encoding sequence includes type and encoding length information, enhancing parse and search operation performance. The type system includes elements for creating complex structured data-text sequences, and a mechanism for application defined extensions.
