Translate to UTF-8 (Unicode class)
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
%utf8Stream = unicode:UnicodeToUtf8([InsertBOM=bool])])
- %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.
Exceptions
This function can throw the following exception:
- CharacterTranslationException
- If the method encounters a translation problem, properties of the exception object may indicate the location and type of problem. See CharacterTranslationException exception class.
Usage notes
- For more information about UTF-8 conversions, see Unicode#UTF-8 and UTF-16.
- The UnicodeToUtf16 method converts a Unicode string to UTF-16.
- The Utf8ToUnicode method converts a UTF-8 Longstring byte stream to Unicode.
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
