Describe the bug

the language name is not visible on top of markdown code blocks, for some languages,
like: 'racket', 'as3', or 'custom'. Its not fixed even if I set code = { enabled = false } in the config.atleast

test.md

Expected behavior

even if language is a rare or custom name, it should show the name.

Icons are retrieved from the icon provider, in your case nvim-web-devicons. If one isn't defined for the language then we have no icon to show.

[ckjoris]

I don't care about icons, would disable them if I could. But problem is no language name is shown.

[MeanderingProgrammer]

Added the ability to disable icons here: 8ee2701

Use this configuration:

require('render-markdown').setup({
    code = { language_icon = false },
})

The behavior in general is a little different, so now if an icon isn't available we'll still show the language.
