> "\x[200b,308]".chars 1 Here I've put an umlaut on a zero-width space, making a single grapheme. This is a bug: these codepoints do not form a single grapheme cluster. U+200b has General_Category=Format, so per UAX #29 qualifies as Grapheme_Cluster_Break=Control, so should always have a grapheme cluster break after it, regardless of the following character. -zefram
