php url encode issue

Jien nibgħat email html fuq l-attivazzjoni tal-utent b'token li nikkodifika b'kodiċi ().

Allura l-link jidher fl-email bħal dan:

<a href="http://site.com/auth?action=confirmActivation&amp;user=79&amp;token=zlKoFo%22f%27g%3FtUb%27%29Z~L1%25zKh%5EG%23_Aj%5Ckbbbd4fdb9121b50f643f12c937ab1c03d5f09861" target="_blank">Click here to activate your account</a>

Meta madankollu nagħmel ikklikkja fuq din il-link, l-url tal-paġna tiegħi tidher hekk:

http://site.com/auth?action=confirmActivation&user=79&token=zlKoFo%22f%27g%3FtUb%27%29Z~L1%25zKh^G%23_Aj%5Ckbbbd4fdb9121b50f643f12c937ab1c03d5f09861

So-token qabel (dan jidher kif jidher fl-email tiegħi) :

zlKoFo%22f%27g%3FtUb%27%29Z~L1%25zKh%5EG%23_Aj%5Ckbbbd4fdb9121b50f643f12c937ab1c03d5f09861

Token wara:

zlKoFo%22f%27g%3FtUb%27%29Z~L1%25zKh^G%23_Aj%5Ckbbbd4fdb9121b50f643f12c937ab1c03d5f09861

Jidher li l-browser tiegħi jagħmel xi konverżjoni awtomatikament meta nikklikkja? Għaliex?
