How to get the full string from JsVar string?

I want to get the full string dsafsafsafdsafdsafdsafdsafdsfdsafsafsafd­sfsafsafsafdsaf from JsVar string as follow, but the function jsvAsString() seems to make the string truncated short, any good way to solve the problem? use JsvStringIterator iterator through the JsVar?
any simple way?
thax!

JsVar *hc = jsvNewFromString('dsafsafsafdsafdsafdsaf­dsafdsfdsafsafsafdsfsafsafsafdsaf');
JsVar *pStr = jsvAsString(hc);
jsiConsolePrintf("%s ", hc);
jsiConsolePrintf("%s ", pStr);
