Sometimes the characters in our webfont are rendered as symbols instead of normal text. It only seems to affect Chrome v42 and v43 on Windows systems.
This is how it looks like when the problem occurs: screenshot.
The site in question: http://www.ne.se (the screenshot is from the footer)
It does not happen on all pages on the site, and deactivating javascript seems to "fix" the problem. One strange thing is that it only seems to be affecting single words, it never happens when there are two or more words together. It seems to be quite random, sometimes it takes a few reloads (without cache) to trigger the problem.
All tips and pointers are welcome as I have yet to find a similar issue elsewhere.
