In Western locales, the local character set is usually an 8-bit superset of ASCII. For most applications, I/O with character...
The directionality value of undefined char values is DIRECTIONALITY_UNDEFINED. Note: This method cannot handle supplementary characters. To support all Unicode characters, including supplementary characters, use the #getDirectionality(int) method. Added in 1.4. Java documentation for java.lang.Character.get...
