debug hover string variable ...more appears

[kzhui125]

	s1 := "你好"
	s2 := "abc"
	fmt.Println(s1)
	fmt.Println(s2)

hover on s1, I get message "你好...+4 more"

“你好” is expected.

That more is coming from https://github.com/Microsoft/vscode-go/blob/0.6.84/src/debugAdapter/goDebug.ts#L823

For s1, delve returns a string with length 6. The string itself is of length 2 and so the +4.

If anyone wants to take a look at how to fix this, then PRs are most welcome.

Hi Ramya. I am looking for something to help the vscode-go extension and I came across this issue. I have the debugging the debug adapter running and see the code in goDebug.ts hitting as you noted.

I am still trying to figure out why delve returns a string with length 6 even though the string is only length 2. Id be happy to submit a PR for this issue just a little confused on what the expected outcome of this issue is.

@xmattstrongx

len("你好") is 6
len([]rune("你好")) is 2

Looks like 6 is for the number of bytes and 2 is the number of characters.
Thanks for that link @kzhui125!

This fix is now out in the latest update (0.6.85) to the Go extension. Thanks @xmattstrongx!
