BloombergLP::bdlde::Utf8Util::numCharactersIfValid

Return the number of Unicode code points in the specified string if it contains valid UTF‐8, with no effect on the specified invalidString. Otherwise, return a negative value and load into invalidString the address of the byte after the last valid Unicode code point traversed. string is necessarily null‐terminated, so it cannot contain embedded null bytes. Note that string may contain less than bsl::strlen(string) Unicode code points.
