Re: Detect katakana characters in java?

OK, this is not specifically i related, but I'm encountering this trying to talk to the i.

How do you check a String to see if it contains Japanese characters (double or single byte)?

If you have a String you can iterate it and simply look at the unicode value for each character (the fancy stuff with code points is still beyond my comprehension).

If we talk about a decoding issue of a byte stream, you most likely need to provide more information.

(and if you happen to have a person who can read Japanese then generate a small file named snippet.xml looking like

<foo>&#char1;&#char2;....</foo>

(where char1 is the numeric value of the character at position 1 in your string, char2 is at position 2 etc). An example would be:

<foo>&#65;&#66;&#67;</foo>

You can then open snippet.xml in Internet Explorer or Firefox and see a rendered version. You should see <foo>ABC</foo>

Hopefully this helps :)
