Does the Go tool has any warning system for look alike Unicode
characters.

In rustc -

Which context do you mean? You said "the Go tool." Do you mean
something in the tool, or do you mean something in the language?

For the tool, when does this come up?

For the language there is some relevant discussion in
https://golang.org/issue/20706.

I don't know why I wrote this. I saw somewhere a post on rustc giving
help message in case error was produced due to use of look alike Unicode
characters like Greek question mark in place of ;

I thought that is cool.

I am sorry.

No need to apologize. It's an interesting idea. There is nothing
similar in Go today.

I was going to ask, "how do they define/measure that?", decided to look at the Rust code, and found http://www.unicode.org/Public/security/10.0.0/confusables.txt

So there's a defined source and everything.
