Minecraft supports two-way chat communication via the 0x03 chat message packet.

Character Set

Minecraft loads its internal 8-bit character set from fonts.txt in minecraft.jar. Ignoring the first line then stripping newlines, the file lists characters 32-255 in order. It follows ASCII for values under 0x80.

The character set is as follows:

" !\"#$%&'()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\\]^_'abcdefghijklmnopqrstuvwxyz{|}~⌂ÇüéâäàåçêëèïîìÄÅÉæÆôöòûùÿÖÜø£Ø׃áíóúñѪº¿®¬½¼¡«»"

This list encapsulates all characters that are in the fonts file. Characters outside of this are acceptable, but are rendered differently.

Font

Minecraft has two fonts types: Default (default.png) and Unicode(glyph_XX.png). Default will fallback on unicode characters if they are not provided (default only has the first 256 glyphs). The minecraft client calculates the widths of the default font type on startup whilst the sizes of the unicode type are provided in glyph_sizes.bin. Each byte in glyph_sizes.bin contains the start and end position of each character, the top nibble (0xF0) is the start position and the bottom nibble (0x0F) is the end position (relative to the characters position in the font sheet).

Example: https://gist.github.com/TkTech/dff9bbe54c9a074612e1

Control Sequences

The client treats certain two-character sequences specially. The first character must be:

  • § (U+00A7) for minecraft
  • & for minecraft classic

The following character indicates a certain colour or formatting to apply to the proceeding text.

The Notchian client expects that an escape code in a chat message will be followed by at least one character, and will otherwise crash with a StringIndexOutOfBoundsException. The workaround for servers is to never end a message with a color control character.

Colors

These correspond very roughly to the colors available in ANSI terminals.

e.g.: This is white, but §4this is dark red

Styles

Like the color codes above, style escape codes are created by combining § (U+00A7) with one of the following characters. Style codes can be combined (except for "r") to enable multiple effects at once. Using any color codes will reset the current style back to plain (unknown if this is a bug or intended behavior). The "r" plain style code will also reset the current chat color back to white (may also be a bug). The "k" random style code is used for the "§kFUNKY LOL" message in /title/splashes.txt inside minecraft.jar.

Sample Code Style
Random chat.gif k Random
Bold chat.png l Bold
Strikethrough chat.png m Strikethrough
Underlined chat.png n Underlined
Italic chat.png o Italic
Plain chat.png r Plain White
