Function std.utf.isValidDchar

Returns whether c is a valid UTF-32 character.

'\uFFFE' and '\uFFFF' are considered valid by isValidDchar, as they are permitted for internal use by an application, but they are not allowed for interchange by the Unicode standard.

Prototype

bool isValidDchar(
  dchar c
) pure nothrow @nogc @safe;
