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

The Utf8ToUnicode function is available as of version 7.3 of the Sirius Mods.

Utf8ToUnicode syntax

  %unicode = string:Utf8ToUnicode                                                                            

Syntax Terms

%unicode
A string variable to receive the method object string translated to Unicode.
string
A String or Longstring that is presumed to contain a UTF-8 byte stream.

Exceptions

This intrinsic 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.

Usage Notes

  • Utf8 and Utf16 has more information about UTF-8 conversions.
  • The Utf16ToUnicode method converts a UTF-16 byte stream to Unicode.
  • The UnicodeToUtf8 method converts a Unicode string to a UTF-8 Longstring byte stream.

Examples

In the following fragment, Utf8ToUnicode converts a hexadecimal input to a single Unicode character. In case the Unicode character translates to an EBCDIC character that cannot be displayed, the CharacterEncode option of the UnicodeToEbcdic method causes the output of a hexadecimal character reference. The 'X' constant function is used in the example.

   %u Unicode                                                                             
   %u = 'E284A2':X:Utf8ToUnicode                                                          
   Print %u:unicodeToEbcdic(CharacterEncode=true)                                         
                                                                                          

The result of the above fragment is the character reference for the trademark character:
