2.2.2.1 Codepage Data File Format
The Readme.txt (as specified in [UNICODE-README]) provides details about the codepages files and the file format. This section specifies information about the pseudocode of mapping UTF-16 strings to earlier codepages by taking the content from the Readme.txt.
Each file has sections of keyword tags and records. Any text after ";" is ignored as blank lines. Fields are delimited by one or more space or tab characters. Each section begins with one of the following tags:
CODEPAGE ([UNICODE-README])
CPINFO ([UNICODE-README])
DBCSRANGE (section 2.2.2.1.3) (DBCS codepages only)
DBCSTABLE (section 2.2.2.1.3) (DBCS codepages only)
