Set the value to nonzero if the conversion should be lenient. By default, the conversion is strict (i.e. not lenient).<p>
If the conversion is strict, the converter stops at the first invalid byte (on decoding) or at the first character not supported by the coding system (on encoding). If this happens, <code>MConverter-&gt;result</code> is set to <code>MCONVERSION_RESULT_INVALID_BYTE</code> or <code>MCONVERSION_RESULT_INVALID_CHAR</code> accordingly.<p>
If the conversion is lenient, on decoding, an invalid byte is kept per se, and on encoding, an invalid character is replaced with "&lt;U+XXXX&gt;" (if the character is a Unicode character) or with "&lt;M+XXXXXX&gt;" (otherwise).     </td>

Set the value to nonzero before decoding or encoding the last block of the byte sequence or the character sequence respectively. The value influences the conversion as below.<p>
On decoding, in the case that the last few bytes are too short to form a valid byte sequence:<p>
If the value is nonzero, the conversion terminates by error (MCONVERSION_RESULT_INVALID_BYTE) at the first byte of the sequence.<p>
If the value is zero, the conversion terminates successfully. Those bytes are stored in the converter as carryover and are prepended to the byte sequence of the further conversion.<p>
On encoding, in the case that the coding system is context dependent:<p>
If the value is nonzero, the conversion may produce a byte sequence at the end to reset the context to the initial state even if the source characters are zero.<p>
If the value is zero, the conversion never produce such a byte sequence at the end.     </td>
