filter tracks with v2.3UTF in order to change to ISO

How can I find all tracks with v2.3UTF tags in order to change them to v2.3ISO tags?

You can create a new column 'Character Encoding' via View > Columns... where you use


as value to display within this column.

After that, just sort this column by clicking on the column header.

Yes, that's it, thanks a lot.
I wasn't aware of this functionality, how can I find more such things? Is it in the help somewhere, or do you just need to know....

It's from the help: Customize the file list.
