hi @RAVI KOPPARAPU ,
I've come across this problem and found out, that there are even more special ("invisible") characters that are causing problems in the component tWriteJSONField.
I built my own program to delete these unnecessary values. In case you want to keep them try to escape them with backslash:
In the routine I replaced as follows:
public static String removeControlChar(String input) {
input = input.replaceAll("\u0000", ""); //remove control character NUL (hex value 0x00)
input = input.replaceAll("\u0002", ""); //remove control character STX (hex value 0x02)
input = input.replaceAll("\u000b", ""); //remove control character VT (hex value 0x0B)
input = input.replaceAll("\u000e", ""); //remove control character SO (hex value 0x0E)
input = input.replaceAll("\u000f", ""); //remove control character SI (hex value 0x0F)
input = input.replaceAll("\u0010", ""); //remove control character DLE (hex value 0x10)
input = input.replaceAll("\u0003", ""); //remove control character ETX (hex value 0x03)
return input;
}
