Font character issue on MacOS

[CallumHoward]

Hi,

I believe I have found an issue with font rendering on MacOS. The same code works fine on Windows 10. The issue is that symbols are rendered as questions marks when a font is loaded from a file path. Here is a screenshot of the problem:

As you can see, the period (.) character is rendered as a question mark. I tested other common ascii symbols, some of them work and some of them don't.

My setup:
libcinder on master (a6dc85ba1)
MacOS 10.14.4
MacBook Pro 2012, NVIDIA GeForce 660m/Intel HD 4000

Steps to reproduce:

1. Change code to the following in the sample BasicApp.cpp on line 38

    auto config = ui::Options().font(getAssetPath("ProggyClean.ttf"), 12);
    ui::initialize(config);
    //ui::initialize();

2. Copy ProggyClean.ttf (found in the imgui/misc/fonts directory) or another font to the assets folder.

i'm experiencing the same issue. Did you find a workaround in the end?
