Minecraft wiki entry for Language, associated text: It has some of the Unicode characters. These characters are stored in ascii.png, accented.png and nonlatin_european.png file. If a character is typed (e.g. in chat, on a sign, in a book, etc.) that isn't either in these files, the font changes to Minecraft's "Unicode font" (stored in unicode_page_nn.png) that has thinner lines. The "Unicode font" supports the "BMP" (Basic Multilingual Plane) section of Unicode characters, from 0000 to FFFF (decimal 65535), which is also limited, because it's only a part of Unicode characters, not all of them.‌[Java Edition only]
