Description
Code
I tried this code with cargo doc:
/// This is a test:
/// ```ASN.1
/// foo
/// ```
fn main() {
println!("Hello, world!");
}I expected to see this happen: rust doc generated without any warnings.
Instead, this happened:
warning: unexpected character `.`
--> src/main.rs:1:1

1 | / /// This is a test:
2 | | /// ```ASN.1
3 | | /// foo
4 | | /// ```

= note: `#[warn(rustdoc::invalid_codeblock_attributes)]` on by default
"ASN.1" is supported by Linguist. I also see the same result if I specify any codefence languages that include special characters (e.g. C++, C#).
