A DESCRIPTION OF THE PROBLEM :
Java encodes its strings as UTF-16 characters. This means in most cases a single symbol can fit within 1 char (16 bit). But when the java string is to represent a unicode symbol which is encoded as 32 bit in UTF-16, it will be stored as two consecutive chars in the string.
HTMLEditorKit treats this as 2 characters instead of combining it into one when using write method.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1.Create HTMLDocument\
2. Insert this string into its body "𠜎𠜱𠝹𠱓𠱸𠲖𠳏"
3. Save it using HTMLEditor write method


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Html contains "𠜎𠜱𠝹𠱓𠱸𠲖𠳏"
ACTUAL -
Html contains 14 dummy symbols
