Hello, I think the topic has been raised a few times, and it seems impossible to escape :: inside the cloze content. This is particularly troublesome when the close contains computer code (usually inside pre and/or code html tags) since this makes the usual workarounds with html escapes as   unusable. At the moment I used the similarly looking ⁚⁚ (two dot punctuation) symbol.
the :: symbol is unfortunately very common in various programming languages (eg. C++, Rust).
is there any proposals to work on this? I think the cloze syntax could be augmented to specify different escapes without breaking backwards compatibility.
What do you think?
