A modern programming language that makes developers happier.

kotlinlang

Why is that a thing in Kotlin?
```val url = "<https://google.com/>"
val rgxReplace = url.replace("/".toRegex(), "\\/")
val strReplace = url.replace("/", "\\/")
    
println(rgxReplace)  // outputs: <https://google.com/>
println(strReplace)  // outputs: https:\/\/google.com\/```

In the regex example I should replace with `"\\\\/"` to get a similar result

You have to deal with 2 levels of character escaping: 1 for the string literal, and 1 for the regex.

So it expects the replacing to also be a regex? In what use case would that be a thing?

Another thing, I'm writing something like that to implement escaping for the `/` character in Gson serialization. My backend needs that, although I'm slightly concerned about possible side effects like breaking Base64.

To get a literal `\` in regex, you need to escape it: `\\`. To get a literal `\\` in a Kotlin string, you need to escape both: `\\\\`.

<@U4FEKT18W> You can use raw-strings to avoid double-escaping:

```url.replace("/".toRegex(), """\\/""")```
