Disclosed is a method for persisting an offline address book in a Unicode compatible format without changing the underlying file formats, record representations, and low level string comparisons. By storing the text information in UCS Transformation Format-8 (UTF-8), Unicode strings can be represented in 8-bit widths and thus are interpreted as just another multi byte character representation. Additionally the offline address book files can still be efficiently searched using the same algorithms for text searching as long as the search key is converted to UTF-8 first.

Systems and methods are described for efficiently processing, searching and/or rewriting variable width encoded data, such as UTF-8 encoded data, will be described. Embodiments of the systems and methods modify and adapt search algorithms, such as the Horspool and Wu-Manber algorithms, to efficiently process and manage searching of variable width encoded text in large blocks of text, such as text that may be carried via a stream of packets thru a network device, such as an intermediary device.

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 entropy 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.
