I'm trying to format something in latex - but some unicode characters don't render and some are out of order. I'm rendering with xelatex like this `xelatex --shell-escape file.tex`

.

```

Are you using the lstlean file?

#### Chris Hughes (Jun 18 2020 at 05:58):

There's a list of symbols in that file, if things don't display correctly after using lstlean, then you can add to the list of symbols.

#### Billy Price (Jun 18 2020 at 06:52):

Yes I am. phi is already in that file, and that's the first symbol to not show up

#### Kevin Buzzard (Jun 18 2020 at 06:54):

Those `'`

s are not the best either

#### Billy Price (Jun 18 2020 at 06:58):

In fact I just went back to compiling the sample.tex file provided there and even that's missing unicode symbols. There seems to be no complaint in the log

#### Billy Price (Jun 18 2020 at 06:58):

Actually there is a warning "Package inputenc Warning: inputenc package ignored with utf8 based engines."

#### Billy Price (Jun 18 2020 at 07:08):

Is there a recommended way to compile tex files that use lstlean? I'm using XeLaTeX because I read it was necessary for unicode characters, but I'm realising this might be the problem.

#### Sebastian Ullrich (Jun 18 2020 at 07:53):

IIRC `listings`

has some issues with Unicode even on other Latex engines(?). I always use minted with Luatex for my talks.

\makeatother

#### Alexandre Rademaker (Feb 10 2021 at 23:37):

Hi @Sebastian Ullrich , have you use minted with beamer? any sample I can see?

#### Sebastian Ullrich (Feb 11 2021 at 08:24):

@Alexandre Rademaker Nothing beamer-specific, but I recently documented everything I know in https://leanprover.github.io/lean4/doc/syntax_highlight_in_latex.html
