AdditionalMapping contains a slice of all string transformers chained together which is used as additional mapping for PRECIS profile.

var BigramRecombineTransformer transform.Transformer = &bigramRecombineTransformer{}

BigramRecombineTransformer is a Unicode stream transformer object which removes all leading and trailing white-spaces, then it reduces all inter-word white-spaces into a single normal space.

var PrecisProfile = precis.NewFreeform(
	precis.FoldWidth,
	precis.AdditionalMapping(func() transform.Transformer {
		return transform.Chain(AdditionalMapping...)
	}),
	precis.FoldCase(cases.HandleFinalSigma(true)),
)

PrecisProfile is a Unicode PRECIS profile which prepare strings for a more secure comparison.

var RemoveRepeatedMarksTransformer transform.SpanningTransformer = &removeRepeatedMarksSpanningTransformer{}

RemoveRepeatedMarksTransformer is a Unicode stream transformer object which removes repeated Thai ascending and descending marks except the first.

var Sanitize = factory.MakeStringTransformFunction(
	PrecisProfile.NewTransformer(),
)

Sanitize extends on the LatinExtendedSanitize by additionally sanitize an input string containing Thai scripts.
