FontData.h:265:1: narrowing conversion of '-96' from 'int' to 'char' inside { }

[yurivict]

Build fails on FreeBSD on the powerpc64 architecture. The port got flagged with this error message.
I'm not sure which compiler is this, I didn't seethe error myself.

I just ran into this error when compiling for ARMv6 (Raspberry Pi Zero W) using Gnu compilers version 6.3.0.

1. cmake -G"Unix Makefiles" -DCMAKE_BUILD_TYPE=Release
2. make

The fault appears to lie in building the Gwen third party library in my case.

That solved this problem for me and while I understand why demos may not work on an ARM device, the author of the issue would probably prefer to have them. I am having other issues, but will post them in a separate Github issue at a later time if I cannot find an answer in previous issues. Thanks yurivict.
