Multiterm not recognizing "Nº" term nor "n.º" nor anything similar

Hi

My glossary has entries to match "nº" or"n.º" term (meaning number or paragraph - in Law documents) = "paragraph"

But this is the only term not shown in term recognition

i changed term settings of "Enable recognition of two-letter terms" to Active (Ticked)

Any ideas why this could be happening?
