ABSTRACT:
Detecting an encoding system used to encode computer readable text or data across a wide variety of encoding systems. When a user attempts to download and use text or data on his or her computer, encoded data is passed from the desired text or data file to a series of code readers. Each code reader is programmed to read encoded data according to the rules of a given encoding system. When a given code reader is unable to validate a byte of data according to the encoding system rules associated with that reader, that reader is deactivated. This process of elimination leads to a single reader and a single encoding system. If the list of readers is not eliminated to a single reader, ambiguity resolution is performed to narrow the list of readers to a single reader. Once the list of active readers is narrowed to one, the encoding system associated with that reader is returned as the encoding system with which the data is encoded. Finally, statistics gathered on the data as it is read are used to confirm and augment detection of the encoding system.
