Pokémon in the games Pokémon Black and White are stored in a 136 byte or 220 byte structures. All unencrypted values are stored in little-endian format. The game encrypts the data when it is stored in the save file. Party Pokémon have additional values to hold current battle stats and conditions.

Nickname and OT Name
Since generation 5, the nickname and OT name are encoded with Unicode instead of a game-specific character map. However, there are some exceptions, which are listed below. Note that unlike generation 4, the last two bytes of are always 0xFFFF, even if there already was a terminator before. Exceptions to this rule are the Roaming Pokémon, Starters, and various gifts and in game trades, in which the OT name does not have the escape sequence.
There are no normally occurring trash bytes for generation 5 Pokémon, but the Poké Transfer will keep existing trash bytes (except the last two) even if the Pokémon evolves in generation 5. In the advent of a different language Pokémon evolving in another language game, characters not overwritten are left as trash bytes.
Characters that can be replaced in Unicode
In the game, those are half-width versions of existing Unicode characters used in non-japanese versions with long name support.
