Font file missing in demo

[manuels]

demo prints

LaTeX Font Warning: Font shape `OMS/cmr/m/n' undefined
(Font)              using `OMS/cmsy/m/n' instead
(Font)              for symbol `textbraceleft' on input line 98.

Obviously one more file has to be imported into the virtual filesystem of emscripten to make the italic font work correctly. Which file is it?

Thanks for the hint. I tried to include this package, but the warning stayed.

I am seeing a similar (but fatal) error when I try to run the demo.

That seem to be a different error and is somehow caused by truncating pdftex.map. If you remove all the lines above the cm* lines it works.

I don't know yet why the file is truncated and how to solve it, maybe someone has an idea?

[fzimmermann89]

It seems to be caused by gzip. Disabling it on the server solves the issue for me.

The reason is that emscripten will interpret the content-length in the response header as the length of the file and truncates it.

To fix it there should be a patch in emscripten..

[fzimmermann89]

I will submit a PR to emscripten. In master it should be fixed, so there should just be an update of the demo. You can visit fzimmermann89.github.io/texlive.js/ for a Wirkung demo

[fzimmermann89]

The issue should be solved with https://github.com/kripken/emscripten/commit/89b3661ff6427132c4fcfe55f7689af9ae85fcb2

@fzimmermann89 I get a similiar error to @coventry. Ist there a solution to this?

Edit Nevermind I used @fzimmermann89 texlive.js which works out of the box like a charm ;)

[fzimmermann89]

Ok, I just started writing down some questions for troubleshooting - then I saw your edit... :D

[MariusHerget]

@fzimmermann89 I am currently trying to use Arial (UArial) in my project but I am getting a similar error message. Any ideas about how to solve it?
