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:
