This is so strange. I was dead sure I tried that but it failed
for some reason. But after trying it just now it also seems to
work just fine. Thanks! :)

If you have a string, and you _know_ that it's only ASCII, then
either use representation or byCodeUnit to wrap it for the call

Hi,
I'm having some trouble sorting the individual characters in a
string. Searching around, I found this thread

1) You don't need to convert char[] to string via to. No. Too
much. Cast it.
2) You don't need byKey, use foreach key, value syntax. That

Hi,
This is my first post on Dlang forums and I don't have a lot of
