(this+is+the+value+in+%24a) (this+is+the+value+in+%24a)+äöüäöü%3F%3F%3F%3C%26%2B++
What is the EscMode? 2 Now a Url: Here it goes 0 Now lets look what we are getting from this:
(this is the value in $a) (this is the value in $a) äöüäöü???<&+
What is the EscMode? 0 Now a Url: Here it goes 3 Now lets look what we are getting from this:
(this is the value in $a) (this is the value in $a) äöüäöü???<&+
What is the EscMode? 3 Now a Url: Here it goes What is the EscMode? 3 file.html?name=abcd&data=xyz Now we localy set $escmode:

(this is the value in $a) äöüäöü???<&+
(this+is+the+value+in+%24a)+äöüäöü%3F%3F%3F%3C%26%2B++
(this is the value in $a) äöüäöü???<&+
