> {{JsonWriter}} of {{JsonTemplateLayout}} works on {{char}}\-by\-{{char}} basis, even while truncating excessive input. This approach might leave the truncated string in a state such that the last {{char}} (which will be followed by {{truncatedStringSuffix}}) might be the high surrogate of a surrogate pair. This incomplete {{char}} needs to be removed.
