Android Studio writing BOM's to UTF-8 file

Question

I am working on a project where all the source files are encoded as UTF-8, to please the java compiler (otherwis, it will spit out errors on other encodings). Everytime I save a source file with Android Studio, it will write a Byte Order Mark on the file, preventing the compilation from succeeding. How can I fix this?

As a workaround, I am manually deleting the BOM with a Hex Editor but it gets really annoying.

Answer 1

Remove BOM Didn't work for me.

It's the problem for the code I copied from a website.

I wrote it again and problem solved.

Answer 2

It seems that this is a bug in IntellJ IDEA, on which Android Studio is based.

Try this:

1. In Settings | File Encodings Select the "Projekt"-Entry with the mouse in the second column and choose "" (Confrim removal of Encodings set in subdirectories or choose the directories where you don't wan't a default-encoding enforced.)
2. de-select "Autodetect UTF-encoded files"
3. select "Transparent native-to-ascii conversion"

(Reference for above)

Another possible fix is to remove all BOMs outside Android studio (with hex editor or another text editor) and then choosing File -> Synchronize in AS.
