I write a custom util method to format money strings,
it relies on string.Format("{0:n}", someValue).
I cover it with unit tests to verify it works, and when I run them
I get this little gem:
It turns out that the whitespace returned from string.Format is character 160, whereas the whitespace you normally get is character 32.
So I change my method to replace all char 160 into char 32, and voila! all the tests pass...
what's up with that? I didn't even know there were two chars in .Net that both returned whitespace...
