Pan-language font in WebGL increases build size and load time by 100%

I'm trying to localize my WebGL game. I need to use a font that covers most/all languages (including Chinese). I cannot use the user's local system fonts, as that is not supported in Unity-WebGL.
Currently I'm including "DroidSansFallback.tff" in the build, which has a huge filesize of 2.9MB (The smallest font I could find which covers the Unicode Basic Multilingual Plane).
The font doubles the size of my build, and has a huge load-time impact for my game on some browsers.

I need to solve this problem.

I've considered downloading the font externally and in parallel with the Unity build, to help speed up the process.
But unfortunately, I can't put a ".tff" file in an asset bundle ("Unrecognized assets cannot be included").
I can get the font directly using WWW, but I can't find a way to turn a byte array representing a font into a UnityEngine.Font object.

If anybody has experienced this issue, or has any advice or tips, it would me much appreciated!

 

I'm running into the same problem here trying to localize a webgl build, does anyone have advice?

 

I'd be interested in this too, anyone find a way to at least keep the font resource outside of Unity, adding fonts to the English version massively increasing the file size to support other languages seems like a very poor option.
