Still having trouble with "," and "."

Dear @Emre, I configured both screens in regional settings in windows:


so when I try to add a discount:




If I invert the “,” and “.” in both configuration…


This is the rule I am using:


and of course, when I change the “,” and “.” I also change the \, or \. in in:

[?Desconto;\d{2}?\.\d{2}?;;CON;49,50,51|52,53,54|55,56,57|8,48]

This seems to me a strange behaviour, and I cannot remember now why I am writing this, but I had some trouble… as soon as i comes back to my mind, I will add it to this post…
