Java FRANCE/FRENCH Locale thousands separator looks like space but not actually

Question

If I convert a number in FRANCE/FRENCH locale it should use space as thousands separator. If I try to replace the spaces with some other characters, it does not find any spa

Answer 1

It is \u00a0 the non-breaking space, which makes sense for an amount. (Imagine € 40 at the end of a line, and the next starting with 000.) The same holds for some other languages.

input = input.replace('\u00a0', '.');

Answer 2

As suggested by Joop Eggen in his answer It is \u00a0 the non-breaking space.

As a work around, I got the thousand separator as follows

String input = NumberFormat.getNumberInstance(Locale.FRANCE).format(123123123);
System.out.println("String after conversion in locale "+input);

DecimalFormat df = (DecimalFormat) NumberFormat.getNumberInstance(Locale.FRANCE);
DecimalFormatSymbols symbols = df.getDecimalFormatSymbols();
char thousandSep = symbols.getGroupingSeparator();

input = input.replace(thousandSep, '.'); 

It worked as expected

String after conversion in locale 123 123 123
After replace space with dot      123.123.123
