Pascal Schumacher commented on TEXT-40:
---------------------------------------

Issue moved from commons-lang to commons-text, as StringEscapeUtils was ported to commons-text and will soon deprecated in commons-lang.

> 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.
