Error building Player: unmappable character for encoding ascii

Hi, I am getting these errors when I try to create an android apk.

Error building Player: CommandInvokationFailure: Failed to recompile android resource files. See the Console for details.
C:\Program Files\Java\jdk1.6.0_37\bin\javac.exe -bootclasspath "G:/adt-bundle-windows-x86_64-20131030/sdk/platforms/android-19\android.jar" -d "G:\Projects\MOTD\development\MOTDGit\Temp\StagingArea\bin\classes" -source 1.6 -target 1.6 -encoding ascii "com\gamevil\motd\R.java" "com\google\android\gms\R.java" "com\google\example\games\basegameutils\R.java" "com\google\example\games\mainlibproj\R.java"

stderr[
com\gamevil\motd\R.java:354: unmappable character for encoding ascii
        /**  Application Manager ?????? ????????? ?????? 
                                 ^

        /**  Application Manager ?????? ????????? ??????

This happened right after integrating the Google Play Games plugin (GitHub - playgameservices/play-games-plugin-for-unity: Google Play Games plugin for Unity).

I don’t know why it is forcing ascii or what other plugins of the project may creating some conflict.

Someone could help me to understand why this happens or how to fix it?

Thanks.

Hi, could you please file a bug on the issue and attach the R.java file that is causing this error?

You need to look for the code near this string

“/** Application Manager”

in the R.java file. You will find non-ascii characters in there.
