Problem: Can't get Unicode character to print correctly.
Here is my grammar:
options { k=1; filter=true;
// Allow any char but \uFFFF (16 bit -1)
charVocabulary='\u0000'..'\uFFFE';
}
ANYCHAR :'$'
| '_' { System.out.println("Found underscore: "+getText()); }
| 'a'..'z' { System.out.println("Found alpha: "+getText()); }
| '\u0080'..'\ufffe' { System.out.println("Found unicode: "+getText()); }
;
Code snippet of main method invoking the lexer:
public static void main(String[] args) {
SimpleLexer simpleLexer = new SimpleLexer(System.in);
while(true) {
try {
Token t = simpleLexer.nextToken();
System.out.println("Token : "+t);
} catch(Exception e) {}
}
}
For input "ठ", I'm getting the following output :
Found unicode:
Token : ["à",<5>,line=1,col=7]
Found unicode:
Token : ["¤",<5>,line=1,col=8]
Found unicode:
Token : [" ",<5>,line=1,col=9]
It appears that the lexer is treating Unicode char "ठ" as three separate character. My aim is to scan and print "ठ".
