Use the unicode ellipsis character:

If it is ok, I'll do the application related changes as a follow up patch?

OK. Since Samsung does not use Chromium's UI (as far as I know), you don't have
to modify the UI code aside from making it compile and making sure that all
tests pass. I can take care of making it look good.

I'm working on it here https://codereview.chromium.org/2281913002/.

All currency formatting should happen in CurrencyStringFormatter.java.

currency = currency.substring(0, MAX_CURRENCY_CHARS - 1) + ELLIPSIS;

That way a 7 character currency is truncated into 5 characters + ellipsis. (If
you have enough space to show 6 characters + ellipsis, then might as well just
show the full 7 characters.)
