[fpc-pascal] fpWeb and html and uri escaping/unescapingelements

You should not unescape recursively.
Input to EscapeHTML: '<' Output: '&lt;' : Correct
UnescapeHTML: input  '&lt;' Output '<'   Wrong.
This is because you replace '&' with '&' resulting in '<' which is
translated to '< ' in the next line.

Un/escapeHTML parsing must be in one go, specially the "&amp" one. Test


I'm not sure what you mean here.

If you have already html entities you should not escape them. If you do not
have html entities you should escape them.
The Escaping and unescaping works well, I already tested them before I sent


Right unescape "<", your code "<".
