Processing UTF-8 data

When you need to process UTF-8 data, first convert the 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:

  1. Use the function NATIONAL-OF to convert the ASCII or EBCDIC string to a national (UTF-16) string.
  2. Use the function DISPLAY-OF to convert the national string to UTF-8.

The following example converts Greek EBCDIC data to UTF-8:

This image shows sample code for converting Greek EBCDIC data to UTF-8. Link to detail.

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.
