Invalid rune literal syntax generation for class matcher

[sno2]

Given this grammar:

ox80_oxBF <- [\200-\277]

The generated grammar code has a syntax error saying more than one character in rune literal:

var g = &grammar{
	rules: []*rule{
		{
			name: "ox80_oxBF",
			pos:  position{line: 1, col: 1, offset: 0},
			expr: &charClassMatcher{
				pos:        position{line: 1, col: 14, offset: 13},
				val:        "[\\200-\\277]",
				ranges:     []rune{'\u0080', '┬┐'}, // <- error here
				ignoreCase: false,
				inverted:   false,
			},
		},
	},
}

Thank you for your work.

I got this:

		{
			name: "ox80_oxBF",
			expr: &charClassMatcher{
				val:        "[\\200-\\277]",
				ranges:     []rune{'\u0080', '¿'},
				ignoreCase: false,
				inverted:   false,
			},
		},

It seems ok:

ord('¿')
191

ord('\277')
191

@fy0 Seems like something spooky is going on... I am on Windows using the latest release. What are you on?
