However, in the Unicode range, there are certain codepoints that are not
considered characters. The Unicode standard reserves the last two
codepoints in each Unicode Plane (U+FFFE, U+FFFF, U+1FFFE, U+1FFFF,
- U+2FFFE, etc.), as well as 16 codepoints in the range U+FDD0..U+FDDF,
+ U+2FFFE, etc.), as well as 32 codepoints in the range U+FDD0..U+FDEF,
inclusive, as non-characters. If any of those appear in the string, they
may be discarded and will not appear in the UTF-8 representation, or they
may be replaced by one or more replacement characters.
Non-characters are codepoints that the Unicode standard reserves and must
not be used in text interchange. They are the last two codepoints in each
Unicode Plane (U+FFFE, U+FFFF, U+1FFFE, U+1FFFF, U+2FFFE, etc.), as well
- as 16 codepoints in the range U+FDD0..U+FDDF, inclusive.
+ as 32 codepoints in the range U+FDD0..U+FDEF, inclusive.
