Code unitsĬode points are internally stored as code units. The code points contained in astral planes are called astral code points.Īstral code points are all points higher than U+10000. Worth noting that planes 3 to 13 are currently empty. The other 16 planes are called astral planes. The first is special, it’s called Basic Multilingual Plane, or BMP, and contains most of the modern characters and symbols, from the Latin, Cyrillic, Greek scripts. Instead of grouping them by type, it checks the code point value: Plane In addition to scripts, there is another way that Unicode organizes its characters: planes. The full list is defined in the ISO 15924 standard. Latin (contains all ASCII + all the other western world characters).There is a script for every different character set: ScriptsĪll the Unicode supported characters are grouped into sections called scripts. This document is written in UTF-8, for example.Ĭurrently there are more than 135.000 different characters implemented, with space for more than 1.1 millions. UTF-8 is definitely the most popular encoding in the Unicode family, especially on the Web. Unicode defines different characters encodings, the most used ones being UTF-8, UTF-16 and UTF-32. Its meaning depends on the character encoding used. A code point takes the form of U+, ranging from U+0000 to U+10FFFF.Īn example code point looks like this: U+004F. Unicode maps every character to a specific code, called code point. Its aim is to provide a unique number to identify every character for every language, on any platform. There are lots of character sets which are used by computers, but Unicode is the first of its kind to aim to support every single written language on earth (and beyond!). Here is a full example that might get you going: public static void main(String.Unicode is an industry standard for consistent encoding of written text. Updating your code as G suggested (and your edit) should work.
Using java -Dfile.encoding=UTF-8 -jar your-jar-file.jar works. After some major discussion in G's answer!
