Hello I’ve been trying to package my project to android (ETC1) and I get the following errors ``` UATHelper: Packaging (Android (ETC1)): UnrealBuildTool: C:/Users//Documents/Unreal Projects/ProyectoAlfaBackup/Intermediate/Plugins/Android_ETC1/NativizedAssets/Intermediate/Build/Android/UE4/Development/NativizedAssets/Module.NativizedAssets.3_of_5.cpp(6,10) : fatal error: UTF-16 (LE) byte order mark detected in 'C:\Users\\Documents\Unreal Proj UATHelper: Packaging (Android (ETC1)): UnrealBuildTool: 1 error generated.

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 ---

Hi there, The presence of non-ASCII characters in a Blueprint function graph name will currently lead to this issue in 4.18.0, with Blueprint nativization enabled for certain platform targets where the compiler toolchain does not support UTF-16 encoded source files. The suggested workaround for now is to avoid using non-ASCII characters in the Blueprint function name if possible until this can be addressed. This issue should eventually become available for tracking here: [Unreal Engine Issues and Bug Tracker (UE-51910)](https://issues.unrealengine.com/issue/UE-51910). Hope this helps! ---

While that could be the root of the issue, but I checked - all my function/variables/etc names are within standard ASCII characters (latin keyboard). ---

Agreed, however in that post I noticed that for the “GetТехт\_Attributes” function it appears the ‘Техт’ substring consists of non-ASCII characters. ---

I’m having the same issue in 4.19, in my project.cpp file. However there are no non-ASCII characters in the file or the name of the file… ---

I had Cyrillic ‘C’ in the name of the icon files instead of the Latin ‘C’. They look the same, but they are 2 different symbols. Avoid file names and function in bluprints other than English.
