* This prevents other plugins from trying to process the id (like node resolution),
* and core features like sourcemaps can use this info to differentiate between
* virtual modules and regular files.
* `\0` is not a permitted char in import URLs so we have to replace them during
* import analysis. The id will be decoded back before entering the plugins pipeline.
* These encoded virtual ids are also prefixed by the VALID_ID_PREFIX, so virtual
* modules in the browser end up encoded as `/@id/__x00__{id}`
