Errors from font files in demo

[zackcmartin]

I've set up the demo, but when I type something as simply as "x+y" I am getting error messages like so:

block of char: 43 is 0
FILE: /home/code/cLaTeXMath/src/fonts/fonts.cpp, LINE: 191, FUNCTION: getChar, MSG: { char: x, font id: 2, path: res/fonts/base/cmmi10.ttf }
FILE: /home/code/cLaTeXMath/src/platform/cairo/graphic_cairo.cpp, LINE: 45, FUNCTION: loadFont, MSG: Load font: res/fonts/base/cmmi10.ttf, count: 32766
Null pattern

I found a similar issue here

what OS do you use? I can't reproduce this issue on my PC, this seems like the font file is corrupted, can you open the cmmi10.ttf via your font viewer?
