Create iTextSharp PDF in Android

I am making a report in Unity3D with iTextSharp. When I start app from Unity it creates PDF and works perfect. But when I build App on Android device, I have a problem with creating font. Here is what I do:

BaseFont bf = BaseFont.CreateFont(System.IO.Path.Combine(Application.streamingAssetsPath, "ADOBEARABIC-BOLD_0.OTF"), BaseFont.IDENTITY_H, false);

As I have seen, the first parameter for font creation is the path to the font. My font is in

/Assets/StreamingAssets/

folder.

When I try to load it with WWW class, it can find it, but when I give just the path to the creator it won’t work.

Any idea what should I do? Or is there any other way to create a font that supports Arabic characters?

EDIT:

Ok, I have somehow managed to get to the font. First I copy font from Assets to the root of the APP:

IEnumerator CopyFiles()
    {
        string fromPath = Application.streamingAssetsPath + "/";
        string toPath = Application.persistentDataPath + "/";
        string filesNamesToCopy = "ADOBEARABIC-BOLD_0.OTF";
        WWW www1 = new WWW(fromPath + filesNamesToCopy);
            yield return www1;
        File.WriteAllBytes(toPath + filesNamesToCopy , www1.bytes);
    }

And then I make BaseFont:

BaseFont bf = BaseFont.CreateFont(System.IO.Path.Combine(Application.persistentDataPath, "ADOBEARABIC-BOLD_0.OTF"), BaseFont.IDENTITY_H, BaseFont.EMBEDDED);

Now I get new error when try to build on Android device:

ArgumentException: Encoding name ‘windows-1252’ not supported Parameter: name

Here is solution to my problem:

Did you tried to copy DLL to project folder as it is written in this post?

Because I don’t need custom font,
only font that can post special characters,
I load it from system font directory directly on android device.
Maybe, you will get a font that suits to your need in that directory also.
After that I register it with FontFactory and it works!

Hope you will get some help from my solution.
