This is due to the limitation of node-api. napi_set_named_property and ``napi_set_named_propertyconsider\0` as terminator rather values.

To solve the problem, we first use the workaround:

• Convert the String to a custom string type that implements ToNapiValue trait and convert the String to JsString under the hood.

This way would cause a extra napi call for creating JsString.

The best practice is to make node-api napi_set_named_property and napi_set_named_property support passing string with length to treat \0 as values instead of terminator.
