If the program uses UTF-8 or UTF-16, it must work on any valid Unicode code point,
|
|
whether in the [https://en.wikipedia.org/wiki/Plane_%28Unicode%29#Basic_Multilingual_Plane Basic Multilingual Plane] or above it.
|
|
|
|
The program must reference logical characters (code points), not 8-bit code units for UTF-8 or 16-bit code units for UTF-16.
|
|
|
|
Programs for other encodings (such as 8-bit ASCII, or EUC-JP) are not required to handle all Unicode characters.
