Variable CodePagesConst

Type Declaration

• getCodepageCharList: function

  • getCodepageCharList(encoding: string): string[]

    Build the 128-character lookup table for byte values 0x80–0xFF in a given code page.

    Two strategies are tried in order:

    1. data array — use the explicit character table bundled in capabilities.json (each entry covers 16 characters; 8 entries total).
    2. iconv-lite — decode each byte 128–255 using the python_encode name via iconv-lite (requires the encoding to be supported).

    Parameters

    • encoding: string

      Encoding name or alias (e.g. "CP437").

    Returns string[]

    Array of 128 single-character strings covering bytes 0x80–0xFF.

    Throws

    LookupError if neither strategy succeeds for the encoding.

• getEncoding: function

  • getEncoding(name: string): CodePageEntry

    Retrieve the CodePageEntry for a given encoding name or alias.

    Parameters

    • name: string

      Encoding name or alias (e.g. "CP437", "pc850").

    Returns CodePageEntry

    The matching CodePageEntry from the capabilities database.

    Throws

    Error if the encoding is not found in the database.

• getEncodingName: function

  • getEncodingName(alias: string): string

    Resolve an encoding alias to its canonical name.

    Handles common variants such as "pc437" → "CP437", "latin1" → "ISO-8859-1". Unrecognised inputs are returned uppercased without modification.

    Parameters

    • alias: string

      Encoding name or alias (case-insensitive).

    Returns string

    Canonical encoding name as used in capabilities.json.
