Some unicode symbols in Julia code cause failed process

[jessebett]

Having a code block with unicode symbols like ∇ or ŷ cause the latex compilation to break for both XeLaTeX and LuaLatex.

I tried following various stackoverflow about adding packages for unicode math or unicodex encodings into the latex template with no success.

How can I have the unicode symbols that are valid Julia code not break Weave?

Latexify.jl has a function for converting unicode to latex commands. I'm not at all sure that this is relevant but I thought I'd mention it in case it helps.

[jessebett]

That's not going to help here because these are typsetting the code blocks which use (probably?) verbatim environments. So we're not trying to typeset julia code to math environment which is what Latexify is doing.
