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:
