<div><p>Using FMTOPT(*MAP) to copy to a UTF-8 character or UTF-16 graphic field
|
||
|
|
converts the data in the from-field CCSID to the CCSID of the UTF-8 character
|
||
|
|
or UTF-16 graphic to-field. If the length after conversion is less than the
|
||
|
|
length of the UTF-8 or UTF-16 graphic to-field, the field is padded. If the
|
||
|
|
length after conversion is greater than the length of the UTF-8 character
|

or UTF-16 graphic to-field, the field is truncated.</p>
|

|
|
<p>Using FMTOPT(*MAP) to copy from a UTF-8 character or UTF-16 graphic field
|
||
|
|
converts the data from the CCSID of the UTF-8 character or UTF-16 graphic
|
||
|
|
field to the CCSID of the to-field. If the length after conversion is less
|
||
|
|
than the length of the to-field, the field is padded. If the length after
|
||
|
|
conversion is greater than the length of the to-field, the field is truncated.</p>
|
||
|
|
<p>UTF-8 or UTF-16 conversion possibilities also include variable length fields.
|
||
|
|
Generally, the result length of a variable length to-field will be the minimum
|
||
|
|
of the from-field converted length and the maximum length of the to-field.</p>
|
||
|
|
<p>The CCSID conversions created when copying from or to a UTF-8 or UTF-16
|
||
|
|
field might cause the byte length of the data to be different after the conversion.
|
||
|
|
The maximum length of the to-field is used to determine if all of the converted
|
||
|
|
data will fit in the to-field.</p>
|
||
|
|
<p>When copying from a UTF-8 or UTF-16 field to a character field, or to a
|
||
|
|
DBCS-either field where the first byte is already converted to a valid SBCS
|
||
|
|
character (not a shift-out X'0E'), any remaining characters that cannot be
|
||
|
|
converted to SBCS (actual double-byte data in the UTF-8 or UTF-16 field) will
|
||
|
|
have a single-byte substitution character set in its place.</p>
|
||
|
|
<p>When copying from a UTF-8 or UTF-16 field to a DBCS-only, DBCS-graphic
|
||
|
|
field, or to a DBCS-either field where the first byte is already converted
|
||
|
|
to a DBCS shift-out (X'0E'), any remaining characters that cannot be converted
|
||
|
|
to DBCS will have a double-byte substitution character set in its place.</p>
|
||
|
|
<p>To be successful when using FMTOPT (*MAP) to convert from or to a UTF-8
|
||
|
|
or UTF-16 data, the resulting converted data for the to-field must conform
|
||
|
|
to the to-field type. Otherwise, conversion errors will occur and the to-field
|
||
|
|
will be set to its default value.</p>
|
||
|
|
<p>FMTOPT (*MAP) has to be specified when you copy from a non-normalize file
|
||
|
|
to a normalize file. The to file will be a normalize file in any cases described
|
||
|
|
in the following table:</p>
