How to use small spaces as number separators in Android?
To make it easier for users to know the exact score, I wanted to separate my three numeric blocks with tiny spaces (Unicode: SIX-PER-EM SPACE).
I want 1∼241∼234 instead of 1241234.
I tried
DecimalFormat formatter = new DecimalFormat("# ### ### ### ###");
String score = formatter.format(getHighscore());
Unfortunately, the code gives me an error. How do I put my 6 em spaces in my number?

Solution
You receive an exception:
Caused by: java.lang.IllegalArgumentException: # ### ### ### ### at
java.text.DecimalFormat.initNative(DecimalFormat.java:564)
I don’t think it’s possible to pass spaces to this constructor.
I have a different code to suit your needs :
DecimalFormat formatter = (DecimalFormat) NumberFormat.getInstance(Locale.US);
DecimalFormatSymbols symbols = formatter.getDecimalFormatSymbols();
symbols.setGroupingSeparator('\u2008');
formatter.setDecimalFormatSymbols(symbols);
Log.e("Formatted: ", formatter.format(1241234));
