It slices by codepoints? That's just silly, so we've gone through this whole unicode everywhere process so we can stop thinking about the underlying implementation details but the api forces you to have to deal with them anyway. Fortunately it's not something I deal with often but thanks for the info, will stop me getting caught out later.
