JUNK characters or special characters are passed when sending request from ajax/javascript to servlet + multipart form data

Special characters / Junk characters while sending data from jquery ajax to servlet while uploading file

Hi recently I received a weird issue is while setting description of a record it appended some weird special characters in my string. 

Inorder to solve this issue what we can do is 

use item.getString("UTF") instead of item.getString().

Python dictionary example

emp={
 
  'name':'anil',
  'age': 18,
  'sex':'male'
 
}
for item in emp.values(),emp.items(),emp.keys():
  print(item)
for key,value in emp.items():
    print(key,value)
