Special characters in Output names when performing Analysis in new Map Viewer

[MappyIan]

This is more a rant than a question.

In the old Map Viewer (now called 'classic'), when running analysis your output dataset names could include hyphen and bracket/brace characters.  In the new Map Viewer, if you include a hyphen or bracket/brace character in the name of the output dataset you get the following message:

However, if you visit the page linked in this message (https://doc.arcgis.com/en/arcgis-online/analyze/perform-analysis-mv.htm#ESRI_SECTION1_5EACA346CAB14E...), the hyphen and bracket/brace characters are not included in the list of disallowed characters:

Aaaaaaaaaaaaaaaaaaaaaaargh.

This is either a documentation error or a bug in the Analysis tools in the new Map Viewer.  Either way, it's really annoying.

The doc will be updated to include the missing characters. Sorry for the confusion. You can track this bug that was logged: BUG-000159958

Thanks @RussRoberts, that bug only mentions the bracket/brace characters though: [ ] (), it doesn't mention hyphens.  You can't have hyphens in output layer names either.  I think it's probably worth adding a note to the bug so that hyphens are mentioned too.  I was looking at the details here: https://support.esri.com/en-us/bug/unable-to-save-output-layers-when-using-analysis-tools-bug-000159... 

When using the Analysis Tools in Map Viewer Classic you can have bracket/brace and hyphen characters in output layer names.  Plus once you've run the Analysis Tool, you can simply rename the output layers and add in bracket/brace and hyphen characters, so the restriction/limitation seems a little odd/inconsistent with other parts of ArcGIS Online.
