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).
