When I run the Reconcile tool it works fine. Subsequently, I export the results as a python snippet and run it as a standalone script. The script processes and doesn't return an error but the version doesn't reconcile nor delete. I have come across suggestions that the version name should be in Unicode and that this is a known possible bug. Why wouldn't the script work when it obviously ran just fine when using the tool?
arcmap or Pro?
Reconcile Version (Deprecated) or Reconcile Versions (replacement)
There is a list of bugs depending on what you are using in your code vs the tool
PS when running a tool inside ArcWhatever, there are things that are known (permissions, ownership etc) whereas a standalone script doesn't
I didn't realize that there were 2 different Reconcile tools to chose from, I didn't take notice.
I will certainly look at the bugs document.
I ran the tool in ArcMap. Interesting concept about permissions and ownership.
I believe the following applies to me.
Arcpy.ReconcileVersions_management() fails to reconcile version created by operating system authenticated users.
Add  around the version, so for example: ["AVWORLD\cont_joglekar".R1"]
