"Generate Attributes operator: chars allowed in attribute names in expressions"

Which special characters are allowed in attribute names in expressions in the Generate Attributes operator?
From my keyboard I have only been able to find '.', '$' and '_'. Are there any others?

(Background: The reason I am looking for permissible special characters is that I need to copy and paste expressions from another application where I am using the special characters to embed information/parameters into the attribute name.)

Hi,

well, I am actually not 100% sure but from my experience that's pretty much it. I would actually not even use the "." if possible since this might cause problems in other operators using regular expressions for attribute names.

Cheers,
Ingo

Thanks Ingo.

I never thought about the potential issue with '.'. I use it to express hierarchical structure in the name.

Are you referring to operators such as Generate Aggregation, where the user specifies a regular expression for selecting attributes (in which case I can escape the '.' manually), or are there other issues beyond this to watch out for?

Thanks
Isak
