Abstract: CODE PAGE IDENTIFICATION SYSTEM This disclosures relates to a comprehensive method of codifying the different encoding schemes that are used for graphic character representation, resulting in a single identification mechanism that is used in conjunction with a corresponding registry to simply and uniquely identify the scheme used. The mechanism comprises such a short form identifier having the capability of acting as a short form (alias) for its corresponding list of component identifiers; acting as a short form for a collection of specific component identifiers having a specific property; allowing special meanings to be conveyed in relation to tagging of data with the code identification; and allowing bridging to existing systems that use only some components of the code identification.
