bug: Non english standard characters break the raw query

[DagW]

🌧 Describe the problem

Search queries Swedish like letar efter söndriga saker or in spanish with ñ break the raw query, and result in short search strings from .raw

Ex. letar efter söndriga saker -> letar efter s

The default cutFn is overridden with to allow all characters.

I suspect the behaviour comes from isWord in the scanner.

⛅ Expected behavior

Expected behaviour would be to also allow these characters.

🔄 Minimal reproduction

func isWord(ch rune) bool {
	return ch >= '!' && ch <= '~' && ch != ':'
}

func TestIsWord(t *testing.T) {
	fmt.Println(isWord('ñ')) // false
}

I belive thats what the unicode.IsLetter(r) is for?
