json - How to use Groovy JsonOutput.toJson with data encoded with UTF-8? -

i have file utf-8 encoding.

i write groovy script load file json structure, modify , save it:

def originpreviewfilepath = "./xxx.json"  //target file def originfile = new file(originpreviewfilepath)   //load utf8 data file json structure def originpreview = new jsonslurper().parse(originfile,'utf-8')  //here own code modify originpreview   //convert structure json text def resultpreviewjson = jsonoutput.tojson(originpreview)   //beautify json text (indent) def finalfiledata = jsonoutput.prettyprint(resultpreviewjson)   //save jsontext new file(resultpreviewfilepath).write(finalfiledata, 'utf-8')  

the problem jsonoutput.tojson transforms utf-8 data unicode. don't understand why jsonslurper().parse can use utf-8 not jsonoutput.tojson?

how have jsonoutput.tojson use utf-8? need have exact inverse of jsonslurper().parse

i believe encoding applied @ incorrect statement while reading itself.

change below statements :

def originfile = new file(originpreviewfilepath) def originpreview = new jsonslurper().parse(originfile,'utf-8') 

to:

def originfile = new file(originpreviewfilepath).gettext('utf-8') def originpreview = new jsonslurper().parsetext(originfile)
