Shouldn't that be: uint32_t unicode; if (localeinfo.multibyte && 0 <= pcre2_config (PCRE2_CONFIG_UNICODE, &unicode) && unicode)That is, don't bother to call pcre2_config in a unibyte locale, and don't initialize 'unicode' (so that valgrind-like tools can detect an error if pcre2_config is buggy), and check the return value of pcre2_config.
