    It is not easy to solve this issue therefore, I am thinking now to find a way of bypassing it. My friend has suggested me to replace these special characters with the best ones. Website https://xpertwriters.com/academic-ghostwriting-service/ is helpful in research paper online. Using suggested HTML escape characters might help me out.

    Unity Application side:
    Uri.EscapeUriString("Your header content with spéci@l characters");

    Serveur side: PHP exemple:
    urldecode($encodedString);

    Thanks EILIOMM,

    It seems to be really only the brackets... I first tried to escape it in different ways without success.
    In the end I just replaced the brackets and it works.

    [code]
    string Escape(string s)
    {
    s = s.Replace("(", "&#40");
    s = s.Replace(")", "&#41");
    return s;
    }
    [/code]

    I found a way to bypass the issue for those who need the header to work and are stuck with the 2017.x version.

    Simply replace the characters "(" for "&#40" and ")" for "&#41". These are the html escape characters and seem to work fine for me.
