MD5 hash with different results

Question

Im trying to encode some chains to MD5 but I have noticed that:

For the chain: \"123456çñ\"

Some webs like

http://www.md5.net

www.md5.cz

Answer 1

If I try :

echo "123456çñ
";
echo "utf-8 : ".md5("123456çñ")."
";
echo "ISO-8859-1 : ".md5(iconv("UTF-8", "ISO-8859-1","123456çñ"))."
";

It gives the result :

123456çñ
utf-8 : 66f561bb6b68372213dd9768e55e1002
ISO-8859-1 : 9e6c9a1eeb5e00fbf4a2cd6519e0cfcb

The first website encode the string in ISO-8859-1 and the second in UTF-8.
