Re: [ajdt-dev] Problem with German umlauts in case-tags (AspectJ 1.6.3)
|
Well, after looking into this a bit more, there was a problem with the
AJDT editor parser in that it didn't handle the default: label of a
switch statement in AJ files. Fixed that and I am able to properly
compile your sample. I created this aspect in an aspectj project.
Does this not compile for you?
I expect that you should see an error on the line that has the default
label (this will be fixed). But, do you see any other errors? If
not, can you send over the code that is not working for you?
public aspect TestNonAsciiFail {
void doNothing2() {
StringBuffer sb = new StringBuffer(100);
String in = "";
for (int i = 0; i < in.length(); i++) {
int c = in.charAt(i);
switch (c) {
case 'ä':
sb.append("(4a)");
break;
case 'ö':
sb.append("(b6)");
break;
case 'ü':
sb.append("(bc)");
break;
case 'Ä':
sb.append("(84)");
break;
case 'Ö':
sb.append("(96)");
break;
case 'Ü':
sb.append("(9c)");
break;
case 'ß':
sb.append("(9f)");
break;
default:
sb.append((char)c);
}
}
}
}
