Can you provide the raw markdown for your example?

I am seeing the same when you put a slightly indented code block under another code block, but it actually works if I put it under a list. Am wondering if it has to do with how far indented things are.

There's also a separate issue of indented_code_block, which this plugin does not support.

I found something strange. If the indent is 2, the icon will not be missing:

source code is:

Yeah, I found the same thing.

I think I figured out the cause, not even sure why I even tried this, but it seems to be an interaction with indent-blankline.nvim.

If I disable indent blank line then everything starts working as expected, no random cutoff of language.

I'll try to see what's going on there.

[MasouShizuka]

You are right, after I disabled indent-blankline.nvim, I can also see the icon when indent is 4.

[MeanderingProgrammer]

Ah it was a combination of indent blank lines overlaying the leading spaces as well as the code fence capturing the leading space. So when things got concealed they were left shifted then overlayed.

Handling it is pretty straightforward pushed a fix here: 48083f8.

LMK if it works for you as well!

[MasouShizuka]

After taking a quick look at some of my notes, this should be able to display the icon normally.

Sweet, closing the issue, feel free to re-open if you come across something.
