Reproducible: Always

Steps to Reproduce:
<script type="text/javascript">
 document.write(JSON.parse('"\\u0000"').charCodeAt()+'<br/>')
 document.write(JSON.parse('"\\u0001"').charCodeAt()+'<br/>')
 document.write(JSON.parse('"\\u0002"').charCodeAt()+'<br/>')
 document.write(JSON.parse('"\\u0003"').charCodeAt()+'<br/>')
 document.write(JSON.parse('"\\u0004"').charCodeAt()+'<br/>')
 document.write(JSON.parse('"\\u0005"').charCodeAt()+'<br/>')
 document.write(JSON.parse('"\\u0006"').charCodeAt()+'<br/>')
 document.write(JSON.parse('"\\u0007"').charCodeAt()+'<br/>')
 document.write(JSON.parse('"\\u0008"').charCodeAt()+'<br/>')
 document.write(JSON.parse('"\\u0009"').charCodeAt()+'<br/>')
 document.write(JSON.parse('"\\u000a"').charCodeAt()+'<br/>')
 document.write(JSON.parse('"\\u000b"').charCodeAt()+'<br/>')
 document.write(JSON.parse('"\\u000c"').charCodeAt()+'<br/>')
 document.write(JSON.parse('"\\u000d"').charCodeAt()+'<br/>')
 document.write(JSON.parse('"\\u000e"').charCodeAt()+'<br/>')
 document.write(JSON.parse('"\\u000f"').charCodeAt()+'<br/>')
 document.write(JSON.parse('"\\u0010"').charCodeAt()+'<br/>')
 document.write(JSON.parse('"\\u0011"').charCodeAt()+'<br/>')
 document.write(JSON.parse('"\\u0012"').charCodeAt()+'<br/>')
