Description
If already escaped HTML characters are in the input test, they get escaped again using StringEscapeUtils.escapeHtml4().
For example:
If the input is:
100 kg & l t ; 1000kg <without the spaces>
Then the output of escapeHtml4() becomes:
100kg & amp ; l t ; 1000kg <without the spaces>
At my workplace, we felt the need for a method in StringEscapeUtils which does not escape already escaped characters.
I have attempted to create this method. Creating a pull request soon.
