} catch (e) {
  console.log(e instanceof URIError)  // true
  console.log(e.message)              // "malformed URI sequence"
  console.log(e.name)                 // "URIError"
  console.log(e.fileName)             // "Scratchpad/1"
  console.log(e.lineNumber)           // 2
  console.log(e.columnNumber)         // 2
  console.log(e.stack)                // "@Scratchpad/2:2:3\n"
