How to handle the font fix

[dominicbarnes]

I was looking into fixing duojs/duo#438, and I ended up stopping at this lib once I noticed you are intentionally stripping the query/hash portion of the URL.

I'm curious why that's necessary? Is it just to prevent downloading the same file twice?

I think the fix is, we should be stripping it when we search for the file (and copy or symlink), but not when we write the file.
