The context

I'm currently enrolled in a Database course. In that course, we are using RelaX, a relational algebra calculator. In that calculator, you can use UTF-8 characters as operators. The following is an allowed query: π price σ model = 2001 Laptop. There also some other operators: π, σ, ρ, , , τ, γ, , , ¬, =, , , , , , ÷, -, , , , , , , and .

I am working on a homework assignment that involves writing queries in that site. For this reason, I would like to accomplish the following. First, let me introduce some things that would help you understand my question.

I know that it is possible to use UTF-8 characters within my document by using LuaLaTeX.

\documentclass{article}

\usepackage{fontspec}
\usepackage{unicode-math}

\setmathfont[math-style=upright]{XITS Math}

\begin{document}
$A ⨝ B$
\end{document}

enter image description here

I also know that it is possible to typeset inline math in minted environments.

\documentclass{article}

\usepackage{minted}

\begin{document}

\begin{minted}[escapeinside=||, mathescape = true]{text}
foo |$\pi$| bar
\end{minted}

\end{document}

enter image description here

I can put together those knowledges and accomplish the following: Insert UTF-8 characters in minted environments.

\documentclass{article}

\usepackage{fontspec}
\usepackage{unicode-math}

\usepackage{minted}

\setmathfont[math-style=upright]{XITS Math}

\begin{document}

\begin{minted}[escapeinside=||, mathescape = true]{text}
foo |$⨝$| bar
\end{minted}

\end{document}

enter image description here

However, I would like to get rid of the |$ and $| part within the minted environment. Thus, I would be able to copy queries from RelaX to my document without the need of previously formatting the query.

You might be wondering: Why don't I get rid of that part? The problem is that I tried the solution presented here, but, the character is not correctly displayed (see below).

\documentclass{article}

\usepackage{fontspec}
\usepackage{minted}

\setmonofont{CMU Typewriter Text}

\begin{document}

\begin{minted}{text}
This is displayed:

/etc/puppet/hieradata/
├── common.yaml
└── virtual
    ├── false.yaml
    └── true.yaml

This is not correctly displayed: ⨝
\end{minted}

\end{document}

enter image description here

I think this happens because is not supported by CMU Typewriter Text. This leads to my question.

The question

Is there any monospace font supported by LuaLaTeX that would display all those characters that I mentioned (namely, π, σ, ρ, , , τ, γ, , , ¬, =, , , , , , ÷, -, , , , , , , and )

In fact, there's Kurinto Type, part of Kurinto typefaces. Although I doubt about their quality (the author says they are designed to type with MSWord), they cover all the characters you require.

\documentclass{standalone}
\usepackage{fontspec}
\setmainfont{Kurinto Type}
\begin{document}
π, σ, ρ, ←, →, τ, γ, ∧, ∨, ¬, =, ≠, ≥, ≤, ∩, ∪, ÷, -, ⨯, ⨝, ⟕, ⟖, ⟗, ⋉, ⋊ and ▷
\end{document}

  • Thanks for answering! How did you find out that that font defines the JOIN operator? Did you already know that font? – Rodrigo Morales May 15 at 8:53

    @RodrigoMorales There's an utility named albatross (in up-to-date distributions) which allows you to find a symbol invoking, e.g. albatross ⨝ so fonts containing the requested symbol will be shown in the terminal. AFAIK Kurinto fonts aren't part of TeX Live or MikTeX, I knew them for other reasons and by mere chance 😄 – Jairo A. del Rio May 15 at 8:57

    Besides albatross, have a look at dp4 Font Viewer (only Windows). – Javier Bezos May 15 at 10:03

texlive comes with a useful program albatross that shows fonts that have a glyph:

$ albatross 0x2A1D 
        __ __           __
.---.-.|  |  |--.---.-.|  |_.----.-----.-----.-----.
|  _  ||  |  _  |  _  ||   _|   _|  _  |__ --|__ --|
|___._||__|_____|___._||____|__| |_____|_____|_____|

                    Unicode code point [2A1D] mapping to ?                     
┌─────────────────────────────────────────────────────────────────────────────┐
│ Font name                                                                   │
├─────────────────────────────────────────────────────────────────────────────┤
│ FreeMono                                                                    │
├─────────────────────────────────────────────────────────────────────────────┤
│ FreeSerif                                                                   │
├─────────────────────────────────────────────────────────────────────────────┤
│ Segoe UI Symbol                                                             │
├─────────────────────────────────────────────────────────────────────────────┤
│ Symbola                                                                     │
├─────────────────────────────────────────────────────────────────────────────┤
│ Unifont                                                                     │
└─────────────────────────────────────────────────────────────────────────────┘

so trying FreeMono as a likely monospace

\documentclass{article}
\tracinglostchars2
\usepackage{fontspec}
\setmainfont{Noto Serif}
\setmonofont{FreeMono}
\begin{document}

\begin{verbatim}
This is displayed:

/etc/puppet/hieradata/
├── common.yaml
└── virtual
    ├── false.yaml
    └── true.yaml

This is not correctly displayed: ⨝
\end{verbatim}
\end{document}

produces
