I have a server that works with windows-1252 and I have a problem with characters à, À, í and Í. I need to replace this special characters to a, A, i and I in PHP.
As you can see in the following URL https://www.i18nqa.com/debug/utf8-debug.html this values have the same value: "Ã".
How can I make the replace if it have the same character?
