Will this test ever be run on an actual Chrome OS device (as opposed to on
Linux)? Perhaps, not. 

Just in case the answer is yes,  kSymbolsFontName had better be 'Noto Sans
Symbol" on CrOS. Similarly, kCJKFOntName had better be 'Noto Sans CJK JP' (or
KR, SC or TC). 

(I'm planning to remove DejaVu fonts from CrOS).

It would be much better to have access to Noto indeed, even on Linux.
Unfortunately on Linux we still rely on the bot's/system's/Ubuntu's font
configuration instead of providing our own set at least for testing. I am not
sure whether this test runs on CrOS, probably the bots will tell you once you
remove DejaVu Sans - in that case you can extend the ifdef to put the Noto fonts
in there.
