PyCharm how to change the font of a Quick Documentation window

Question

I am using PyCharm 2016.1 for Windows 7 with its locale set to PRC-Chinese.

In the quick documentation window, the first 2 lines look weird (some Chinese SimSun fonts?). However, the last line is fine.

How to change the font of these odd lines?
(hack some CSS in some jar?)

I already changed the font of the editor to Consolas (its default value was also odd SimSun)

Answer 1

In idea, I will add the code below to idea64.exe.vmoptions, this changes SimSun to Courier New, when the display code in the documentation is at least better, I hope it works for you.
