Googling "multi-byte thousands separator" gives better results. From
those results, it is clear to me that decimal_point and thousands_sep
are strings that may be interpreted as multi-byte characters. The Czech
separator appears to be a no-break space multi-byte character.

My point is that if a multi-byte character appears, it should be
counted as a single character for the purposes of calculating
min-width. Otherwise, the printed representation is too short.
