 object, cast

to type

20.5.10

public static boolean isDefined(char ch)

The result is

true

 if and only if the character argument is a defined Unicode char 

acter.

A character is a defined Unicode character if and only if at least one of the fol 

lowing is true:

It has an entry in the Unicode attribute table.

It is not less than

\u3040

 and not greater than

\u9FA5

.

It is not less than

\uF900

 and not greater than

\uFA2D

.

It follows, then, that for Unicode 1.1.5 as corrected above, the defined Uni 

code characters are exactly those with codes in the following list, which contains

both single codes and inclusive ranges:
