There's on particular replace in vv's vv.pd.134.js:

    for (var att in tmaps) {
        if (typeof(tacts[att]) !== 'undefined') {
            var lm = (typeof(tmaps[att].m) === 'undefined' ? tmaps[att] : tmaps[att].m);
            tacts[att].map = (lm == null ? null : lm.replace(/\}\,\{/g, '}{'));
        }
    }

So in encoded polylines },{ have to be replaced with }{.
