Function std.ascii.isPrintable

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


c The character to test.


Whether or not c is a printable character - including the space character.


assert( isPrintable(' '));  // whitespace is printable
assert( isPrintable('1'));
assert( isPrintable('a'));
assert( isPrintable('#'));
assert(!isPrintable('\0')); // control characters are not printable

// N.B.: Printable non-ASCII Unicode characters are not recognized.
