This function converts a Unicode string to a UTF-8 Longstring byte stream.

The UnicodeToUtf8 function is available as of version 7.3 of the Sirius Mods.

Syntax terms

%utf8Stream A String or Longstring variable to receive the method object string translated to a UTF-8 byte stream.
unicode A Unicode string.
InsertBOM=bool The optional (name required) InsertBOM argument is a Boolean:
  • If its value is True, the "Byte Order Mark" (U+FEFF, encoded as X'EFBBBF') is inserted at the start of the output stream.
  • If its value is False, the default, no Byte Order Mark is inserted.

CharacterTranslationException

Usage notes

Examples

In the following fragment, UnicodeToUtf8 is used to show how the Unicode U+B2 character (superscript 2) is represented in UTF-8. Appending the StringToHex method is useful for viewing the hex values of characters that do not have displayable EBCDIC equivalents.

The U constant function and StringToHex function are used in the example.

%u Unicode Initial('²':U) Print %u:UnicodeToUtf8:StringToHex

The result is:

C2B2
