Seems in some cases, generated MSDF data is only partially there, or just outlines (as the "m" character here).
This results in those characters rendering incorrectly of course.
The "workaround" is adding a few characters to the charset to shuffle it again; but then again one has a chance to now have other missing letters.
Sorry, currently very busy on other project. Can you try compile the latest msdfgen for your own platform and replace the binary inside bin\platfrom eg. win32 and give it another shot?

Is this a known problem? Any ideas? Thanks a lot!
