Function std.utf.isValidDchar
Check whether the given Unicode code point is valid.
bool isValidDchar
(
dchar c
) pure nothrow @nogc @safe;
Parameters
Name | Description |
---|---|
c | code point to check |
Returns
true
if and only if c
is a valid Unicode code point
Note
'\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.
Example
assert( isValidDchar(cast(dchar) 0x41));
assert( isValidDchar(cast(dchar) 0x00));
assert(!isValidDchar(cast(dchar) 0xD800));
