Unicode Range Coding for Cross-Language Data Integrity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a mismatch in data representation between programming languages like C and JavaScript, particularly in compression and cryptography, due to differences in how character string data is handled, leading to potential errors in data processing and display.
Innovation Solution
A method and apparatus for transcoding Unicode character data using a compression algorithm that generates encoded values, employing a base-n range encoder to compress data into UTF-8 or UTF-16 formats, with a code points mapper assigning these values to Unicode code points, and a UTF encoder for efficient encoding and decoding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If character string data is processed as sequential octets in C, then data processing efficiency is improved, but data integrity is lost when interfacing with JavaScript which treats characters as atomic
Solution Approach 1:
The patent introduces UTF-8 and UTF-16 encoding formats as intermediary layers between C's octet-based processing and JavaScript's character-based processing. These encodings provide a standardized mapping between bytes and Unicode characters, allowing efficient byte-level operations in C while preserving character integrity when interfacing with JavaScript through well-defined encoding boundaries and continuation byte patterns.
2Productivity
If compression algorithms operate on binary data without character encoding awareness, then compression efficiency is improved, but character data integrity is compromised
Solution Approach 1:
The patent applies preliminary encoding of character data into UTF-8 or UTF-16 formats before compression. This preliminary action establishes a consistent binary representation with known properties (byte order marks, continuation byte patterns, surrogate pair structures) that compression algorithms can process efficiently while preserving the ability to reconstruct valid Unicode characters after decompression.
3Speed
If cryptographic algorithms process binary data without character encoding management, then cryptographic operation speed is improved, but character data meaning is lost
Solution Approach 1:
The patent employs UTF-8 and UTF-16 encodings as universal interfaces that serve multiple functions: they provide efficient binary representations for cryptographic processing, maintain character semantics through standardized encoding rules, and enable interoperability between systems with different character handling approaches. The encoding's self-synchronizing properties allow cryptographic operations to proceed on binary data while preserving character meaning through the encoding structure.

AI summary
A character data set is compressed with a compression algorithm module of a computer system to generate one or more streams of encoded values. The compression module is configured to compress the character data set with an base-n range encoder to generate one or more streams of encoded values with UTF-8 or UTF-16. A code points mapper assigns the encoded values to code points in a Unicode format. A UTF encoder encodes the streams of assigned encoded values.
