parser can't handle utf-8 characters

[yvz5]

hi all,

I am trying to parse a graphql schema string but get an error:

# Some german Letters: ÄÖÜ
enum UserType {
    USER
    ADMIN
}

"Syntax Error schema (2:6) Expected {, found Name \"UserType\"\n\n1: # Some german Letters: ÄÖÜ\n2: enum UserType {\n        ^\n3:     USER\n"

it looks like the parser can not handle UTF-8 characters. I wonder why ?

you can test it yourself with the following test:

func TestParsesUTF8(t *testing.T) {

	doc := `
                # Some german Letters: ÄÖÜ
		enum UserType {
			USER
			ADMIN
		}
	`
	astDoc, err := Parse(ParseParams{
		Source: doc,
		Options: ParseOptions{
			NoLocation: false,
			NoSource:   true,
		},
	})
	if err != nil {
		t.Fatalf("Parse failed: %v", err)
	}

	if astDoc == nil {
		t.Fatalf("unexpected nil document")
	}
}
