This is a very rudimentary replacement for Valentin Schmidts great shell xtra. Until he releases a D11 version I use this interim version for my various authoring tools.
BUT...
It is only for my personal use in authoring.
It doesn't do any unicode trickery or the like and it does only have one single handler to execute a shell command and return a list.
It may very well work in many cases, but I am not convinced, that I would use it myself in a real project as it simply is a quick and dirty hack and I do know very, very few about xtras programming and c-programming in general.
So be aware, that this xtra is not properly tested!
