The Julia Unicodes mess up latin characters

[davibarreira]

Hello @mossr . First of all, thanks for making this repo available! It's truly great. I'm using it on my package NotebookToLaTeX.jl, and I realized that when I wrote comments in portuguese with latin characters, the text is not rendered correctly.

After some trial and error, I figured out the issue is in the julia_listings_unicode.tex.

I haven't figured out a solution yet. If I do, I'll try submitting a PR.
