PDI 7.1 XML return ok - PDI 8.0 XML bad return

Hi,

Using PDI 7.1, I send to a XML server this: http://10.133.37.12?var=1U5-TRAFO%20A.AE&begin=31032018220000&end=30042018215959&period=ALL

I get this answer: <?xml version="1.0" encoding="UTF-8" standalone="yes"?><recordGroup><period>2591999</period><record><dateTime>31032018220000</dateTime><field><id>1U5-TRAFO A.AE</id><value>177254.911000</value></field></record></recordGroup>

Using PDI 8.0, the same file, it changes the "%20" for "+": http://10.133.37.12?var=1U5-TRAFO+A.AE&begin=31032018220000&end=30042018215959&period=ALL
I get a bad answer: <?xml version="1.0" encoding="UTF-8" standalone="yes"?><recordGroup><period>2591999</period></recordGroup>

I'm not an expert and this is freaking me out :confused:.

These are the steps:

Thanks.
