OkHttp IDNA Mapping Table
=========================

This module contains supporting tools for building the IDNA mapping table.

  val data = loadIdnaMappingTableData()
  val file = generateMappingTableFile(data)
  file.writeTo(File(args[0]))
}

fun loadIdnaMappingTableData(): IdnaMappingTableData {
  val path = "/okhttp3/internal/idna/IdnaMappingTable.txt".toPath()
  val table =
    FileSystem.RESOURCES.read(path) {
      readPlainTextIdnaMappingTable()
    }
  return buildIdnaMappingTableData(table)
}
