Translate to UTF-8 (Unicode class)
UnicodeToUtf8 converts a Unicode string to a UTF-8 Longstring byte stream.
Syntax
%string = unicode:UnicodeToUtf8[( [InsertBOM= boolean])]
Syntax terms
| %string | A String or Longstring variable to receive the method object string translated to a UTF-8 byte stream. |
|---|---|
| unicode | A Unicode string. |
| InsertBOM | The optional, name required, InsertBOM argument is a Boolean:
|
Exceptions
UnicodeToUtf8 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.
Usage notes
- UnicodeToUtf8 is available as of Sirius Mods Version 7.3.
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.
%u unicode initial('²':U) print %u:UnicodeToUtf8:stringToHex
The result is:
C2B2
