Related Issue: #9838

Adds an example, how bracoxide/str-expand handles the escaping char \.

Thanks for this. It's helpful to understand. However, when constructing paths with path join, I'm not sure how to make it work.

On Windows, it's absolutely necessary to add this before the str-expand

| str replace '\\' '\\\\' | str expand

I don't have an idea in this implementation, as I'm mentioned in this comment: #9838 (comment)

I mean, should I skip what's came after the \ in all cases? Or should I skip only the valid characters (such as braces, dots, and commas (the special characters of the brace expansion))?

You need to convince Microsoft to change their \ to /. That's all! 🤣

I'm thinking that path join --escape may be helpful, but I'm not quite sure.

I think this is good since it just shows another example. Thanks!
