Syntax

%string = unicode:UnicodeToUtf16[( [InsertBOM= boolean])]

Syntax terms

%utf16Stream	A String or Longstring variable to receive the method object string translated to a UTF-16 Big-Endian byte stream (that is, any Unicode point U+wxyz results in the pair of bytes X'wx' and X'yz', in that order).
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) is inserted at the start of the output stream. If its value is False, the default, no Byte Order Mark is inserted.

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-16 conversions, see Unicode#UTF-8 and UTF-16.
• The UnicodeToUtf8 method converts a Unicode string to UTF-8.
• The Utf16ToUnicode method converts a UTF-16 Longstring byte stream to Unicode.

Examples

The following fragment shows a successful call of UnicodeToUtf16. The U constant function and StringToHex function are used in the example.

    %u <var>Unicode</var> Initial('&#x31;':U)
    Print %u:<var>UnicodeToUtf16</var>:<var>String</var>ToHex
    Print %u:<var>UnicodeToUtf16</var>(InsertBOM=True):<var>String</var>ToHex

The result is:
