Convert UTF-8 to ISO 8859-1

Hi all!

Any clue about converting UTF 8 to ISO 8859-1 ?.

I have this XML file with special characters but when i post the information to the DB those special characters transforms and the post goes wrong.

<WSInput>
  <message>
    <name>júan</name>
    <first_surname>pérez</first_surname>
    <second_surname>lalala</second_surname>
    <codPostal>12345</codPostal>
    <id_tag>213131</id_tag>
    <phone_number>12334567890</phone_number>
    <ext_phone_number>00000</ext_phone_number>
    <email>jsjsjs@com</email>
  </message>
  <authorization>
    <servicename>xxxxxxxx</servicename>
    <password>xxxxxxxx</password>
  </authorization>
</WSInput>

i'm using this to encode the whole XML

fixedstring = unescape(encodeURIComponent(xml));

but this is a deprecated library.

Thanks a lot in advance!.

Perhaps the iconv node can help out. Example from another topic.
