I would opt for having such an error message.

Yes. In Germany we make either blanks or periods every third digit. What is
written as 1,000,000.01 may be written as 1 000 000,01 or 1.000.000,01 in
Germany. We can, however, use -destring-'s -ignore()- option for that.
A quick survey in our research unit has shown that people in Poland sometimes
use blanks but neither periods, nor komma.
