Thread:Extension talk:WebFonts/Wikis with many languages on one page/reply (5)

Don't forget that the fonts are cached locally on your computer. Concatenating them would negate that. The sizes of the fonts are in the svn repository, but transport compression may apply, and there are multiple fonts for languages (not all of them are downloaded) and some fonts support multiple languages. I don't know any system which would only have font covering the basic English alphabet.
