Error(1,1)illegalcharacter '\ufeff' when compiling on android studio

Question

I got an Eclipse project source code(I was told that on Android Studio, maybe they just confused), and I start to migrating the code to android studio refers to

http://developer.android.com/sdk/installing/migrate.html

But it doesn't work. so I import the project from path directly and it transfers to the android-studio project automatically, but still, something wrong when I am compiling.

Error:(1, 1) error: illegalcharacter: '\ufeff'

the error position refers to

package com.bla.blabla;

Please help me, thanks

Answer 1

That's a problem related to BOM (Byte Order Mark) character. Byte Order Mark BOM is a Unicode character used for defining a text file byte order and comes in the start of the file. Eclipse doesn't allow this character at the start of your file, so you must delete it. For this purpose, use a rich text editor, such as Notepad++, and save the file with encoding "UTF-8 without BOM." That should remove the problem.

Answer 2

On lower-right corner, you can set the file encoding. Select another option than UTF-8

If a popup appear, choose the option Convert.
