<<.from-version "5.1.23">> If the suffix `rawunicode` is present, Unicode characters above 0x80 (such as ß, ä, ñ or 🎄) will be passed through unchanged. Without the suffix, they will be substituted with `\u` codes, which was the default behavior before 5.1.23. Characters outside the Basic Multilingual Plane, such as 🎄 and other emojis, will be encoded as a UTF-16 surrogate pair, i.e. with two `\u` sequences.
