Bugs and inaccuracies

 * Some languages use Unicode fonts when they should not (example: Spanish doesn't, but French does, even though the standard font contains all French characters).
 * Written Arabic uses connected letters, but the letters do not connect (e.g. "اللغة العربية" is written like "ا‌ل‌ل‌غ‌‌ة‌ ا‌ل‌ع‌ر‌ب‌ي‌ة") in the translations.
 * 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.
 * As of 1.6.1, you can use custom (not only translated) splash text by using resource pack.
 * The option for Hebrew reads "אנגלית" (English). It should be "עברית" (Hebrew).
 * Minecraft ' s language option is only for displaying. In some languages (such as Chinese, Japanese and so on) players cannot input text in their languages. This is because Minecraft doesn't support Input method. Such users still use Mods which supports it.
 * Some in-game messages are not translated to any languages.
 * If the language is set to Spanish ( Mexico ) and go to Controls. The game will crash. This only happens in 12w18a

Trivia

 * Minecraft is available in three constructed languages: Esperanto (devised as an international language and spoken fluently by around 100,000 people worldwide), Klingon (an alien language from Star Trek devised by linguist Marc Okrand), and Quenya (one of the Elvish languages devised by J.R.R. Tolkien). It is also available in the joke "language" of Pirate Speak, which is English written in the way a stereotypical pirate talks. Australian English also pokes fun and humorous stereotypes such as naming furnaces "Barbies", slang for barbeques, calling creepers "Bunyips" or calling a Minecart a 'Holden', Holden being General Motor's marque for cars sold in Australia.Also,Latin was added in 1.7.2
 * 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.
