Throughout Pikmin 3, there are pieces of Koppaite text, or text written in the language of Koppai. The language used consists of unique symbols which, together, form words. A parallel between it and the English language can easily be made, given that characters in Koppaite can be mapped to Latin letters, and with that, a direct English message can be obtained. Although largely original, the characters used in the language are similar to Latin characters, but with some changes.
Because the text behind this language cannot be easily deciphered by players who do not know the cipher, sometimes its contents are secretive and special. For instance, on the area selection menu, when the player clicks an area, some mysterious text will appear on the top-left, with what appears to be comments from the developers. The information behind some texts does not seem to match up with reality, indicating that it was true in prerelease versions.
Each character in the Koppaite language can be mapped to one or two English letters. There are only characters for the 26 English letters plus an extra, unknown one. This unknown character only appears on the Mission Mode menu and Bingo Battle menu, and does not appear in Pikmin 3 Deluxe. While its meaning cannot be decided from the context alone, it's possible that it's some kind of placeholder character, considering the same symbol (〓) is used to indicate missing characters in Japanese.
These characters are obtained from the font file in the game's data.
