When you need to process UTF-8 data, first convert the UTF-8 data to UTF-16 in a national data item. After processing the national data, convert it back to UTF-8 for output. For the conversions, use the intrinsic functions NATIONAL-OF and DISPLAY-OF, respectively. Use code page 1208 for UTF-8 data.
You need to do two steps to convert ASCII or EBCDIC data to UTF-8 (unless the code page of the locale in effect is UTF-8, in which case the native alphanumeric data is already encoded in UTF-8):
The following example converts Greek EBCDIC data to UTF-8:
Usage note: Use care if you use reference modification to refer to data encoded in UTF-8. UTF-8 characters are encoded with a varying number of bytes per character. Avoid operations that might split a multibyte character.
