Use GNU Unifont as default SDL font

[BrettDong]

An effective solution to #14814 . All currently supported languages are able to be drawn correctly in this font:

• English
• French
• German
• Spanish
• Portuguese
• Chinese
• Japanese
• Korean
• Russian

I liked Terminus much more. Unifont looks ugly (especially without font blending):

Then how about select default font according to system language? On English OS the game will use Terminus by default, and on non-English OS the game will choose GNU Unifont.

There is Terminus TTF Bold that looks similar to Terminus.

The second solution is to make "SDL Font" an option in game. Players are able to choose the font they would like to use on their own preference. And keep GNU Unifont the default font, to ensure players using different languages can see the UI texts, instead of tofu boxes.

I see now. That wasn't Terminus after all. I've renamed unifont.ttf to unifont.fon and then I got a proper typeface:

Looks like a bug.

@codemime Which OS are you using? How to reproduce the problem?

Which OS are you using?

Ubuntu 15 x64 with Xfce.

How to reproduce the problem?

Simply write "unifont" to the config file and run the game. Then rename unifont.ttf to unifont.fon and run the game again. That's probably Linux specified.
