I saw on an effect line on Moderal, whose @@TYPE@@ is set as "Stórveldi" (whatever that means), that its @@TYPEINITIALS@@ was computed as "SR". Obviously the server failed to recognize that non-ASCII character "ó" is, in fact, a letter rather than whitespace.
If you don't want to go through the effort of using a proper Unicode-aware library to identify character types, it makes more sense to at least assume that all non-ASCII characters are letters, rather than that none of them are.
