Unicode characters in this range are called BMP (Basic Multilingual Plane) characters. 0 used the following primitive types and built-in class types to support Unicode BMP characters in very natural way: The first 256 characters of Unicode—that is, the characters whose high-order byte is zero—are identical to the characters of the ISO Latin-1 character set. However, I can type the accented character in MS Word, then copy and paste into FreeMind, the accented character appears. Syntax : public static final Character. UnicodeBlock. This will make your regular expressions work with all Unicode regex engines. forName () returns the name of Unicode Blocks, which are determined by the Unicode Standards. Such characters are generally rare, but some are used, for example, as part of Chinese and Japanese personal names, and Definition and Usage. char heart = '\u2764'; Bukkit.
