I have tried to double escape them but maybe that was my error - I couldn’t make it work.

Indeed that would be the case. I could try but now I use the native one, as I was pretty certain I wasn’t the only person trying to send paths to tcl :)

>> sys_bashfilename doesn’t convert the (adequately) created windows separator. So I’ll do a character substitutor.

It is. I presume one with the knowledge (deffo not yours truly :)) could put a comment per method.

Oh good call, I’ll go read the source more often. It just strangely feels heavy, but I should just learn it.

Thanks for your help all. Alexandre, I might put a PR in Else with that call to sanitize the path.
