I want to find out if a Chinese character can be displayed, the unidode for it is "\u8D27", how to use the Java Font method canDisplay ? It takes an int, but "8D27" is not an integer开发者_如何学Python, how does it work, do I need another method to translate "8D27" to an int then use canDisplay ? If so how to translate it ?
Edit : To be more precise, how would a method below look like ?
boolean checkFonts(String inputUnicode)
{
... what goes here ??? ...
}
So if I call : checkFonts("\u8D27") , I can get a yes no answer.

8D27 is in hex, so you can write 0x8D27
as a literal.
e.g.
private int codePoint = 0x8D27;
The \uXXXX
syntax represents the character itself at that code point and is used such that you can express Unicode characters in ASCII.
The canDisplay()
method also accepts a char
, so why not just get the first character of the string:
return font.canDisplay(inputUnicode.charAt(0));
And FWIW, you can convert between char
and int
just by casting:
int codePoint = 0x8D27;
char myCharacter = (char) codePoint;
