The select statement doesn’t match “Morve” with “Morvé”.
Is their a built-in filter of some sort or do I need to devise my own?
This is already in the issue tracker.
In the meantime, Panorama X has a function that strips diacritical marks, so you can build your own selection using a formula to do this, for example:
select stripdiacriticals(Name) = "Morve"
