If I need to examine a byte in string for a specific ASCII

recommended method for doing so
if (MyString[0..1])== ???(219)) writeln("ASCII Block found")
I know there's and easy lib function or cast somewhere but
everywhere I've looked it's not jumping out at me.
219 is not an "ASCII Block". You can just do a search for 219 in
your *byte* stream:
auto b = ("hello" ~ cast(char)219 ~
"world").representation.canFind(219);
The "representation" part *very* is important: Without it, you
string will be interpreted as unicode, and there is *not*
actually a 219 codepoint in there.
