Error when packaging project

Hello

I’ve been trying to package my project to android (ETC1) and I get the following errors

I looked up the UTF-16 problem and it seems like it has to do with the encoding of those cpp files. However, I can’t find any option to change the encoding of the automatically generated files (the build tool is set to UTF 8 btw), so I’m kinda lost at this point.

Any help is appreciated
