Dear Sergey, Powertop --html is working fine with the patch applied. I am able to successfully execute the command and get the results. However, still trying to understand the patch and the difference when I changed the 0 to len in while (mbstowcs(NULL,buffer,0) < len) inside src/lib.cpp file. Now, will try to adopt the latest version of powertop for android. Thanks for all the help and sorry for the delay. Regards, Ganapati Bhat
