But there is quite a steep learning curve for newcomers like me.

Agreed. But there is help. E.g. here is a post on how to create an new action:

Actions and batch-operations

How to create a new action? First, create a new action group via Actions > [Actions] Actions or Alt + 6. Then, click on the button [New] New and give your action group an expressive name, e.g., "All tag fields Upper Case". This action group can be applied to the selected files after you have added one or more actions to it. Now, you can create a new action in your action group via the button [New] New and choose the desired action type from the list. At the moment the following action types …

To create an action group, select at least 1 file
In this case create the action group "Replace Accents"
In the action group, click "new" to create a new the action
Select the type "Replace"
Field: _TAG
Search string: `
Replace string: '
Save the configuration with OK.
Now copy this action and set as
Search string: ´
The rest stays the same.
Close the action group by clicking ok until all dialogues are closed.

Now apply a filter and select the files, run the action group and see whether it worked by toggling the filter with F3.
