What version of Go are you using (go version)?

go version go1.10.3 darwin/amd64

Does this issue reproduce with the latest release?

Yes

What did you do?

https://play.golang.org/p/SGSiTfrzD3P

What did you expect to see?

We should expect a range of 37, as there are 37 characters in the string.

What did you see instead?

A range of 38, the special characters, in this case 'Ñ' make the indexes step further

This is not a bug:

https://golang.org/ref/spec#String_types
https://golang.org/ref/spec#For_statements (see the bit about range clauses, specifically for strings)
