To check whether the problem is related to FreeType – no idea about
the WASM translation of it, though – you could the following.

* Compile current git of FreeType in debug mode (for example, by doing
  `make devel`; see `docs/DEBUG` for more).
* Do the same for the FreeType demo programs.
* Extract the font(s) from the PDFs and check them, say, with the
  `ftview` demo program to find out whether there are issues.  You
  might add `FT2_DEBUG=any:7` to the environment to activate debug
  messages.

If you encounter problems please report again.
