// The following functions are a subset of what is available.
// See the data facades for they provide full access to this serialized string data.
// Way string data is stored in blocks based on `id` as follows:
//
// | name | destination | pronunciation | ref | exits
// ^ ^
// [range)
// ^ id + 2
//
// `id + offset` gives us the range of chars.
//
// Offset 0 is name, 1 is destination, 2 is pronunciation, 3 is ref, 4 is exits
// See datafacades and extractor callbacks for details.
