Hi  
I try to make a legend with some Greek symbols and got such error:

```
dvips: DVI file can't be opened: gmt_eq.dvi: No such file or directory
text [ERROR]: gmtplot_latex_eps: Running "sh gmt_eq.sh" returned error 256.
text [ERROR]: gmtplot_latex_eps: Please run it manually to learn what LaTeX packages you are missing.
text [ERROR]: gmtplot_latex_eps: The script and logs can be found here: /var/folders/hm/n_tqlkfd6b16smck88w5q12w0000gn/T/gmt_latex_PMjLL2
text [ERROR]: gmt_map_text: Conversion of LaTeX to EPS failed

```

here is the line that causes the problem:

`S 0.1i c .4c white 0.5p,snow3,- 0.3i x = cos(@%12%a@%%)`

I tried with other way for LaTeX ( and @[) same issue.

Any hint?

Thanks

NB: Running macOS, gmt installed with homebrew and TexLive is installed. All the system is up-to-date.

Does this line work for you ?

```auto
gmt basemap -R0/1/0/1 -JX10c -Bafg -B+t"@[\cos(x)@[" -png test

```

(should produce just a “cos(x)” png)

Hey, yes the example you gave me works, I got the png with cos(x) and a grid below.

@adakite Could you please post your full example or a minimal example so that it’s easier for us to reprodue?

Here is an example that generates the issue:

```
gmt begin legend
gmt set FONT_ANNOT_PRIMARY 12p
gmt legend -R0/10/0/10 -JM6i -Dx0.1i/0.1i+w4i+jBL+l1.2 -C0.1i/0.1i << EOF

G 0.1i
H 14p,AvantGarde-Book Legend
N 2
V 0 1p
G 0.15i
S 0.1i c .8c white 0.5p,snow3,- 0.3i
G -0.2i
S 0.1i c .6c white 0.5p,snow3,- 0.3i
G -0.2i
S 0.1i c .4c white 0.5p,snow3,- 0.3i x = cos(@%12%a@%%)

EOF
gmt end show
```

With Latex and “symbols” (`%@12%symbol letter@%%` should work. Else, the [octal code](https://docs.generic-mapping-tools.org/dev/cookbook/octal-codes.html?highlight=octal+code) for alpha is \141)

```auto
gmt begin legend

Yeah but the issue I post, is what I get instead.
