Hexadecimal URI Encoder

The first:
If you write this simple code
<html><script>alert();</script></html>

It will convert to
data:text/html;utf-8,%3Chtml%3E%3Cscript%3Ealert()%3B%3C%2Fscript%3E%3C%2Fhtml%3E

But when execute in the browser it will convert to
data:text/html;utf-8,<html><script>alert()%3B<%2Fscript><%2Fhtml>

Which is visible by the user if not executed in a iframe.

The second:
After reviewing the code in the ghostbin, i found some useless line
<tr><td><input type="hidden" name="visibility" id="visibility" value="data:text/html;utf-8,"></td></tr>

Solution:
For the first is better off using URI Encoder.

For the second there's no need to fix as the code doesn't do anything.
