Special characters need to be escaped in a Java Web application

I am using Oracle DB to develop Java EE applications

€˜T’ ! “One Chase.†$% & ( ) ' / : ? ` — – _ ‚ " Test

Someone knows what character codes are. How can I escape them? I need to escape them and replace them with blanks

Solution

These characters are a side effect of the code, which does not handle the encoding correctly (assuming that UTF-8 is iso-8859-1 and vice versa) – they are now garbage You need to fix your app to render them correctly There is no need to replace them with spaces or any filtering
