UI: Font-Family Should be configable

[tylzh97]

Describe the bug
Some characters are not displayed properly. Because bindiff trying to use Roboto Mono as the only font, However this font family doesn't support non-ASCII characters. Maybe font-family config can be add into config>main settings>general card.

To Reproduce
Just Open it and open any config window.

Oh wow. Sorry for that. We really only support (and test) US English as the locale.

As a workaround, try setting the font in the config file (in %AppData%\Roaming\BinDiff\bindiff.json):

Setting this to "Segoe UI" for example, works for setting the UI font, but the core problem is that the Java runtime does not have a concept of fallback fonts if characters needed for a locale are not available.

Setting the font to "SimSun" looks ugly for western text, but seems to work (I don't know any Chinese...):

Thanks very much! It works for me. And may I ask are there any plans to include font configuration in the configuration menu in a future release?

I don't see why not. It'd be good to revamp the settings dialog anyways.
