Detected a bug while using Print function in fmt package

[ariain]

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

$ go version = go version go1.12.9 windows/amd64

Does this issue reproduce with the latest release?

I think so yes....

What operating system and processor architecture are you using (go env)?

go env Output

$ go env
set GOARCH=amd64
set GOBIN=
set GOCACHE=C:\Users\Jaina\AppData\Local\go-build
set GOEXE=.exe

What did you do?

fmt.Print(temp.data, ' ')
here temp.data in an int value...

What did you expect to see?

let temp.data is 10
I see 3210

What did you see instead?

Expected output is "10 " ( except "" ) not 3210...

This is working correctly.

See https://blog.golang.org/constants.

Your ' ' is a number, not a string.
