OptionalencodingOverride the text encoding used to decode strings in the source file.
When omitted, converters auto-detect the encoding (DXF reads
$DWGCODEPAGE; DWG reads the header code page). When provided, it wins
over auto-detection — for example 'cp949' (normalized to the supported
'euc-kr' TextDecoder label) for Korean drawings. Applies to
converters that read text in the main thread, such as the native DXF
converter; worker-based converters may ignore it.
OptionalminimumMinimum number of items in one processing chunk.
Defaults to converter-specific behavior when omitted.
OptionalprogressOptional progress callback invoked as conversion stages advance.
OptionalsysSystem variables to override in the database after HEADER is processed.
OptionaltimeoutTimeout for parser web worker operations in milliseconds.
Options for AcDbDatabaseConverter.read.
Keeps the converter read API extensible without growing positional arguments.
