dissect.esedb.lcmapstring.map_string(value: str, flags: MapFlags, locale: str) → bytes

Very basic Python implementation of LCMapStringEx, only supporting sorting keys.

Currently only supports one hardcoded sorting table (the default) and the basic character types.

Parameters:

  • value – The string to map to a sorting key.

  • flags – The flags passed to LCMapStringEx

  • locale – The locale to use for mapping.

Returns:

A sorting key of the given input that should be compatible with LCMapStringEx.

Raises:

NotImplementedError – If an unsupported flag or character is encountered.
