Similar to `readStr.ucs` but will check for a null-terminator determining the end of the string. The returned string will be of _at most_ `length` octets
function (view, offset, length) {
            var trmOffset = lib.locateStrTrm.ucs(view, offset, length);
            if (trmOffset !== -1) { length = trmOffset - offset; }
            return lib.readStr.ucs(view, offset, length);
        }
