The yaz-iconv command and the API as defined in yaz/yaz-iconv.h is a wrapper for the library system call iconv. But YAZ' iconv utility also implements conversions on its own. The table below lists characters sets (or encodings). that are supported by YAZ. Each character set is marked with either encode or decode. If an encoding is encode-enabled YAZ may convert to to the designated encoding. If an encoding is decode-enabled, YAZ may convert from the designated encoding.
