I'm trying to get the mhchem package working on my mediawiki install, but am running into a problem with whitespace. 
Mhchem is set up correctly, and I can access it from the command line, but mediawiki doesn't render anything correctly. After 
further investigation, I found that texvc is stripping the whitespace from each equation before rendering it.

So when I type:
<math>\ce{H+ + OH- <=>> H2O}</math>
on the wiki

The .tex file is:
\ce {H-+OH-<=>>H2O}

How can I preserve the whitespace so that my equations render correctly?
