a variable argument function that uses %.*s to format the StringView contents. (UNICODE wstring_view uses format: '%.*ls' DO NOT print std::string_view using: std::printf("%s", sv.data()) - Will print until '\0' char found. ALWAYS print std::string using c_str(): std::printf("%s", std::string("Hello).c_str()) Check suspicious code In Cogs Logging using RegExp matches: LOG_.*\.data() E.g. probably passing string_view without StringViewFormat. @param sw std::string_view or StringView to print.
