The result is correct, the normal way to find out is to click the source link in the docs. It will bring you here:
[https://github.com/nim-lang/Nim/blob/version-1-2/lib/pure/unicode.nim#L27](https://github.com/nim-lang/Nim/blob/version-1-2/lib/pure/unicode.nim#L27) The reason is that the implementation of Rune is not to be accessed for the user of the library, so the symbol is not exported. And documentation is generated only for exported symbols.
