Editing UTF-32 (section)

== Variants ==
Though technically invalid, the surrogate halves are often encoded and allowed. This allows invalid UTF-16 (such as Windows filenames) to be translated to UTF-32, similar to how the [[WTF-8]] variant of UTF-8 works. Sometimes paired surrogates are encoded instead of non-BMP characters, similar to [[CESU-8]]. Due to the large number of unused 32-bit values, it is also possible to preserve invalid UTF-8 by using non-Unicode values to encode UTF-8 errors, though there is no standard for this. 

UTF-32 has 2 versions for big-endian and little-endian: '''UTF-32-BE''' and '''UTF-32-LE'''.
