Language

The choice of languages is a feature that allows changing languages for people who are not familiar with English. The language menu is accessible via a button in the main menu to the left of the options button, and from the options menu.

Previously, language packs were needed in order to change the in game language. Language packs are obsolete, due to the official implementation of other languages.

Each language also has a font, although most languages share the same font.

Available languages
There are 96 languages, which are, in the order they appear in the menu:

Minecraft's font is made up of a grid of dots (based on a Northern European code page from MS-DOS). Each character supported by the font is between 1 and 6 dots wide, although most are 5. Characters not supported by this font have thinner lines and instead use computer pixels instead of bigger dots. This will also happen when using certain languages, like French. Text is normally white in chat and black on signs, but it can be changed with formatting codes.

History
Here is a table that summarizes the modifications of languages through the updates:

Upcoming languages
Upcoming and still-in-progress translations are listed on the official Minecraft translation project page.

Removed languages
Austrian German was removed from Minecraft temporarily in version 12w01a because German was too similar to Austria German. However, it has been re-included to the game again in version 1.10.

Issues

 * In some languages, the text is too long and overflows the button it is written on.
 * Splash texts are not translated and therefore always show up in English regardless of language setting.
 * As of 1.6.1, you can use a custom (not just translated) splash text by using a resource pack.
 * Minecraft ' s language option is only for text display. In some languages (such as Chinese, Japanese and so on) players cannot input text in their languages. This is because Minecraft doesn't support the Input method of the language. Some users can still use Mods which support it.
 * Alternative language input was partially resolved in 15w34c when was fixed, but still is not functional for all systems.

Trivia

 * Minecraft is available in four constructed languages: Esperanto (devised as an international language now estimated to be spoken by between 100,000 and 2,000,000 people worldwide), Klingon (an alien language from Star Trek devised by linguist Marc Okrand), Quenya (one of the Elvish languages devised by J.R.R. Tolkien) and Lojban (a language created by the Logical Language Group). It is also available in the joke "languages" of Pirate Speak (English written in the way a stereotypical pirate talks), LOLCAT (English written in the way a stereotypical Lolcat talks), and upside down English. Latin is not a constructed language, but it is almost unused in modern times, except in Vatican City for some documents.
 * It is possible to add a custom language pack by modifying the minecraft.jar file, or, as of 13w16a, copying it to the assets/lang folder. In 1.6.1, this functionality was added to resource packs.
 * Random text will only choose random characters with the same width as the original.
 * Certain letters with certain accents are supported by the font, but not all of them. GNU Unifont is used for many languages like French or Pirate.
 * The only 6-dot-wide characters are ®, ~, and @.
