[antlr-interest] getText()

[Jim Idle]

I wouldn't even bother doing this here in the lexer, it is extra work.
Just process the token if you use it later. However:

STRINGLITERAL
      : (QUOTE (ESCAPEQUOTE | CHARNOQUOTE)* QUOTE)
      | (APOS st=EC
		{setText("\"" + $st.text + "\"");}
      ;

fragment EC : (ESCAPEAPOS | CHARNOAPOS)* ;

Should do it (untested).
