Handle MANôA and FALCçN SPA->FRE Gen2 Trades

Transporter remaps certain locale specific chars depending on the source ROM's version.
Since VC can trade between languages, there are 2 Spanish in-game trades that have glyphs subject to remapping, if it's transferred from a French game.

If the spanish trade is transferred from a french game, it must match the mutated string.

ty @Lusamine & helpers :D
