Convert strings -> runes -> slice of runes -> string (UTF-8)

[Ken GoNoob]

I'm trying to get a substring out of a string which may contain UTF-8 characters. I think I've got it correct to the point where I have a list of runes

representing the string as a slice: []int. Is there a better way to convert it back to a string than iterating through the slice and converting to string 1 char/rune at a time?

Read over this material:

http://blog.golang.org/slices

http://blog.golang.org/strings

And take a look at this playground:

Ah, nevermind. Can get it all in a single stmt:

x := string([]rune(mysring)[4:11])

Wrapped this with a check to see that mystring is a valid UTF-8 string.

A substring function can be something like this:
