Hi Jacque,

This is valid JSON (and also valid ASCII).  In JSON, any character in a 
string may be encoded in the form \uXXXX where XXXX is the 4-digit 
hexadecimal representation of a Unicode codepoint.  No textDecode() 
operation is required.

JSONImport() handles this correctly.

1) Create a stack with a field and a button
2) Put the text above into the field
3) Set the script of the button to:

 > local tJson
 > put JSONImport(field 1) into tJson
 > answer tJson["UserName"]

4) Enter browse mode and click the button

You will get an answer dialog displaying "Eduardo Bañuls".
