Utf16ToUnicode (String function)

Convert a UTF-16 Longstring bytestream to Unicode (String class)

This intrinsic function converts a UTF-16 Longstring byte stream to Unicode. The Utf16ToUnicode function is available as of version 7.3 of the Sirius Mods.

Syntax

%unicode = string:Utf16ToUnicode[( [AllowUntranslatable= boolean], - [Bom= utf16BOM])] Throws CharacterTranslationException

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-16 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

• The input UTF-16 stream may contain a Byte Order Mark (U+FEFF). If one is present, that controls the conversion from UTF-16 to Unicode. If a Byte Order Mark is not present, the input stream is considered to be a Big Endian stream, that is, it is the same as if the stream were preceded by the two bytes X'FE' and X'FF', in that order.
• UTF-8 and UTF-16 has more information about UTF-16 conversions.
• The Utf8ToUnicode method converts a UTF-8 byte stream to Unicode.

Examples

In the following fragment, Utf16ToUnicode converts a hexadecimal input to a single Unicode character. The 'X' constant function is used in the example.

%u Unicode %u = '0032':X:Utf16ToUnicode Print %u

The result is:
