Certain Arabic text gets incorrectly shown while other Arabic text gets showed normally?

Question

I'm developing an app with Arabic text in it.. My phone supports Arabic so the text gets displayed correctly.. the weird problem is that: if I copy an Arabic text that i want from a.txt file and put it into an EditText, the EditText displays weird characters, but if I write the SAME text manually (not copy-paste), the text gets displayed normally!!
Here is a picture showing what I mean, the first EditText is the text I wrote manually, and the second is the text I copy-pasted from the .txt file..

Here is the code of the app:

xml file:

  <?xml version="1.0" encoding="utf-8"?>
<LinearLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent" android:orientation="vertical">
    <EditText android:text="EditText" android:id="@+id/editText1" android:layout_width="wrap_content" android:layout_height="wrap_content"></EditText>
    <EditText android:text="EditText" android:id="@+id/editText2" android:layout_width="wrap_content" android:layout_height="wrap_content"></EditText>
</LinearLayout>

I hope you get what I mean, since it wasnt easy to explain this weird (stupid) problem. Thanks.

If you line the setText up, the second is longer than the first, which means it almost certainly contains characters that look like spaces but are actually something else; try UTF-8 encoding the string and comparing them block by block.
