when there is an invalid character in the output codeset while it is valid in the input. However, POSIX requires iconv() to perform an implementation-defined conversion on the character. So, Citrus iconv converts such a character to a special character which means it is invalid in the output codeset. This is not a problem in most cases but some software like libxml2 depends on GNU's behavior to determine if a character is output as-is or another form such as a character entity (&#NNN;).
