PHP `iconv` not working inside a Wordpress site

I'm using the PHP iconv function to convert accented characters to their non-accented correspondents. For example, "ç" becomes "c", "é" becomes "e" and so on...

For example, this code converts the word "ação" to "acao":

<?php
    $filename = "ação";
    $filename = iconv( 'UTF-8', 'ASCII//TRANSLIT', $filename); // convert latin characters
    echo $filename; // shows "acao"

Check the code above here:

However, running the same function inside my Wordpress site, it shows:

a??o

How to fix this?

I'm using iconv inside a custom function of the plugin WP All Import:

To solve this problem I need to insert this instruction BEFORE iconv:

setlocale( LC_ALL, "pt_BR.UTF-8");

Thus, the conversion is done correctly (in my case, because my site is in pt_BR):

<?php
    $filename = "ação";
    setlocale( LC_ALL, "pt_BR.UTF-8"); // fix the locale
    $filename = iconv( 'UTF-8', 'ASCII//TRANSLIT', $filename); // convert latin characters
    echo $filename; // shows "acao"

Correct result:
