BUG: vscode displaying literal ansi color code on windows

[sloxy]

Bug report coming from conversation in #vscode in clojurians slack on April 28/29/30.

When evaluating code in VSCode, ansi color codes are printed in terminal.

For example, instead of just outputting nil, it will output ?[36mnil?[0m

In other (Windows) clients which use lein repl which support color output in terminal, the response text would be colorized correctly(with the ansi color information then removed after use).
Noticable, issue seems to be fundamental to Windows as cmd.exe, Powershell & VSCode terminal all suffer from this issue,

##Other Info
similar to clojure-emacs/cider#275 which was solved client side.

Thanks for taking the time to report, @sloxy . We will see what we can do. :)

using rebel-readline & the instructions from https://github.com/clojure/tools.nrepl/blob/master/README.md, this is what the nrepl server responds with:

cider-nrepl uses puget.printer (cider-nrepl\src\cider\nrepl\middleware\pprint.clj:35) and it doesn't override the default value of print-color which is set to false (puget/printer.clj:99): :print-color false
so looks like this isn't adding the ansi code to the return value either:
