using UTF8Decoded = std::pair<uint32_t, unsigned> |
The Unicode scalar value of a UTF-8 minimal well-formed code unit subsequence and the subsequence's length in code units (uint8_t).
A length of 0 represents an error.

parseScalarValue - A common parsing routine for all flow scalar styles.
It handles line break characters by itself, adds regular content characters to the result, and forwards escaped sequences to the provided routine for the style-specific processing.
UnquotedValue | - An input value without quotation marks. |
Storage | - A storage for the result if the input value is multiline or contains escaped characters. |
LookupChars | - A set of special characters to search in the input string. Should include line break characters and the escape character specific for the processing scalar style, if any. |
UnescapeCallback | - This is called when the escape character is found in the input. |
