Character encoding (Generation I): Difference between revisions

Fixed-length user-input strings are terminated with 0x50. If a fixed-length string is terminated before using its full capacity, the contents of the remaining space are not specified.

Note that 0x7F is a space (" "), not empty. All characters that are not control characters print in one character.

In some contexts, some characters may display differently than suggested below. For example, in the character input table, ^E_D is 0xF0 instead of the [[Pokémon Dollar]] symbol, and in the Pokédex (in English), the feet (') and inches (") marks are 0x60 and 0x61.

Bytes with a dark gray background are not used normally in the English games. Characters with a light gray background are holdovers from the Japanese game but that are not used in the English game.

The full list of characters that are available for user input are: A-Z and a-z, space, and the following: <code>×():;[]^P_K^M_N-?!♂♀/.,</code>.

The game sections off various areas of the tilemap loaded into {{wp|VRAM}} and each character code directly corresponds to a tile in the tilemap. Not all tiles in the tilemap are accessible via character code, but many are.

## The range 0xE0-0xFF includes numbers, some symbols, and more user interface characters. The player-enterable characters {{PK}}, {{MN}}, and gender symbols are also stored here.

Character codes are within the 0x49-0x5F range, with the exception of 0x4D which defaults to tile 4D.

Control characters work by intercepting the tile that would normally correspond to the control character and instead perform a different action whether it be end the text or print a lengthy message.

These control codes control dialogue text placement, paging, etc.

* 0x5F - "dex" - Displays a period and ends the Pokédex entry

These control codes print text defined elsewhere.

* 0x5A - "user" - In battle, the user of a move. Just like "target", "Enemy " will be prepended to the name of opposing Pokémon.

These control codes print a hardcoded string. They are used to decrease the number of bytes to write common strings while still rendering as the correct number of characters.

* 0x5E - "rocket" - Prints "ROCKET"

The lowercase 'm' (0xAC) in the French, German, Italian & Spanish version is stylized differently compared to the English version.

Technically all characters under 0x60 are control characters, the majority of which have the behavior of causing a specific character from the main font (0x80-0xFF) to be printed with a diacritic in the space above it. Those characters that have different, more complicated functions are detailed below.
