I looked at this again this morning:
A simple Java-test fails and shows why:
Doing this:
String va = "12 345,68 €";
NumberFormat nf = NumberFormat.getCurrencyInstance(Locale.FRANCE);
Number n = (Number) nf.parseObject(va);
and you'll see that n is NULL.
Why?
So, here it is:
the String va contains to blanks (" "), which are between 2 and 3, and
between 8 and € as well.
In fr_FR, however, the *grouping separator * is not " ", but it is a
special char for blank (\u00a0).
So, my little test will pass, when the first BLANK is replaced by the
special char...
I thought, that the NumberFormat actually does parse the object for me.
Looks like (for fr_FR) I have to create a *custom parser*... Which is odd, IMO
Now, do this:
String va1 = "12 345,68 €";
NumberFormat nf = NumberFormat.getCurrencyInstance(Locale.FRANCE);
String va2 = nf.format(12345.68));
System.out.println(va1.equals(va2));
and you see, what the issue is...
Anyway, anyone that has an idea on that one?
Thx!
